Question 1

Solve.
-Mr. Lee wanted to keep track of how far he was driving today. He drove to Lodi which was 50.18 miles, then he drove to Merced which was 19.19 miles, then he drove home which was 3.26
Miles. How far did Mr. Lee drive?

Accepted Answer

To find the total distance Mr. Lee drove, add the distances: 50.18 miles + 19.19 miles + 3.26 miles = 72.63 miles.

Question 2

Rewrite the decimal as a fraction in lowest terms.
-0.5

Accepted Answer

0.5 is equivalent to $\frac{5}{10}$, which reduces to $\frac{1}{2}$ in lowest terms. Therefore, the best choice is D.

Question 3

Rewrite the decimal as a fraction in lowest terms.
-$- 0.028$

Accepted Answer

To convert a decimal to a fraction, we count the number of decimal places and place the decimal's digits over a denominator of 1 followed by that many zeros. In this case, we have three decimal places, so we place the digits 28 over a denominator of 1 followed by three zeros, which is 1000. We get: 
$$-0.028 = -\frac{28}{1000}$$ 
We can simplify this fraction by dividing both numerator and denominator by their greatest common factor, which is 4. 
$$-\frac{28}{1000}=-\frac{7}{250}$$ 
Therefore, the answer is D, $-\frac{7}{250}$.

Question 4

Solve the problem.
-The water in a tank weighs 670.33 lb. One cubic foot of water weighs 62.5 lb. How many cubic feet of water are in the tank?

Accepted Answer

To find the volume of water in cubic feet, divide the total weight of the water by the weight of one cubic foot of water: 670.33 lb / 62.5 lb/cubic foot = 10.72528 cubic feet.

Question 5

Solve.
-When Paula set off to drive to her friendʹs house, the odometer read 7728.2 miles. When she arrived at her friendʹs house, the odometer read 7783.4 miles. How far had she driven?

Accepted Answer

To find the distance Paula had driven, subtract the initial odometer reading from the final reading: 7783.4 - 7728.2 = 55.2 miles.

Question 6

Solve.
-Mrs. Lee prepared her grocery list at home. Her list contained the following items with their sale prices: cheese: $4.95; crackers: $2.95; soda: $1.01; hamburger: $2.95; and gum: $0.95. She bought
All of the items at the store except the crackers. How much money did she spend?

Accepted Answer

Mrs. Lee bought cheese ($4.95), soda ($1.01), hamburger ($2.95), and gum ($0.95). Adding these amounts gives $4.95 + $1.01 + $2.95 + $0.95 = $9.86.

Question 7

Solve.
-Annica owes $734.48 on her charge card. She returns for credit items costing $23.44 and $36.43. She makes a purchase for $26.51 and additional purchases of $40.26, $197.02, and $127.82. She then
Makes a payment of $747.45. Find the amount she now owes.

Accepted Answer

Annica's total returns equal $23.44 + $36.43 = $59.87 credit. Her total purchases equal $26.51 + $40.26 + $197.02 + $127.82 = $391.61. 
Her balance before the payment was $734.48, so the total amount she owed before making the payment was:

$734.48 - $59.87 + $391.61 = $1,066.22

After making the payment of $747.45, her new balance is:

$1,066.22 - $747.45 = $318.77

Therefore, the answer is C, $318.77.

Question 8

Solve the problem.
-Over a 6-day period, you administered 10 tablets to a patient. If each tablet contained 0.100 g of the drug acetaminophen, how much acetaminophen did you administer?

Accepted Answer

The total amount of acetaminophen administered is calculated by multiplying the number of tablets (10) by the amount of drug per tablet (0.100 g), which equals 1 g.

Question 9

Solve.
-Nhung bought a dress originally costing $95.68. When she brought the dress to the counter, the agent told her that it was discounted $9.57. What is the sales price for the dress?

Accepted Answer

To find the sales price, we need to subtract the discount from the original price:
$95.68 - $9.57 = $86.11
Therefore, the sales price for the dress is $86.11, which is option B.

Question 10

Solve the problem.
-A person burns 7.2 calories per minute while walking. How many calories will be burned if the person walks for 5 hours?

Accepted Answer

To find the total calories burned, multiply the calories burned per minute by the total number of minutes walked. 5 hours is 300 minutes (5 hours * 60 minutes/hour). Therefore, 7.2 calories/minute * 300 minutes = 2160 calories.

Question 11

Rewrite the decimal as a fraction in lowest terms.
--0.01

Accepted Answer

To convert a decimal to a fraction, we count the number of decimal places and place the decimal part over the appropriate power of ten. Here, we have 2 decimal places, so we put -1 over 100, giving us -1/100. We can further reduce this fraction to -1/100 in lowest terms. Therefore, the correct choice is A: $- \frac { 1 } { 100 }$.

Question 12

Question 13

Rewrite the decimal as a fraction in lowest terms.
-$0.392$

Accepted Answer

$0.392$ can be written as $\frac{392}{1000}$. Simplifying this fraction by dividing both the numerator and denominator by their greatest common divisor, which is 8, gives $\frac{49}{125}$.

Question 14

Solve.
-Mr. Alvarez grosses $500 a week. If his take-home pay is $410.83 $\text { how much money was deductec }$

Accepted Answer

To find the amount deducted, subtract the take-home pay from the gross pay: $500 - $410.83 = $89.17.

Question 17

Solve.
-A machinist has flat metal plate that is 8.242 cm thick. He laminates the metal plate with four more layers that are 3.688 cm, 1.108 cm, 3.756 cm, and 3.593 cm thick. He then grinds off 2.305 cm from
The top of the plate, then 4.189 cm more, and finally another 1.995 cm. Find the new thickness of
The plate.

Accepted Answer

First, we need to find the original thickness of the metal plate after laminating it with the four layers:

8.242 cm + 3.688 cm + 1.108 cm + 3.756 cm + 3.593 cm = 20.387 cm

Next, we need to subtract the amount that was grinded off from the top:

20.387 cm - 2.305 cm = 18.082 cm

18.082 cm - 4.189 cm = 13.893 cm

13.893 cm - 1.995 cm = 11.898 cm

Therefore, the new thickness of the metal plate is 11.898 cm. Option B is the correct answer.

Question 18

Rewrite the decimal as a fraction in lowest terms.
-0.74

Accepted Answer

To convert a decimal to a fraction, we need to write the decimal as the numerator over 1, and then simplify the fraction. Since 0.74 is already out of 1, we can write it as $\frac { 74 } { 100 }$. To simplify the fraction, we can divide both the numerator and denominator by their greatest common factor, which is 2. This gives us the simplified fraction of $\frac { 37 } { 50 }$. Therefore, the answer is choice C.

Question 19

Solve the problem.
-A stockbroker sold 5 shares of stock for $35.92 each. What was the total amount of the sale?

Accepted Answer

To find the total amount of the sale, multiply the number of shares by the price per share: 5 shares * $35.92 = $179.60.

Question 20

Rewrite the decimal as a fraction in lowest terms.
-0.0004

Accepted Answer

0.0004 can be written as $\frac{4}{10000}$ by recognizing it as 4 ten-thousandths. Simplifying $\frac{4}{10000}$ by dividing both numerator and denominator by 4 gives $\frac{1}{2500}$.
