Question 5

Find the gross pay at the given rate. Round to the nearest cent.
-31.7 hours at $11.25 per hour

Accepted Answer

To find the gross pay, we need to multiply the rate per hour with the number of hours worked. 
Gross pay = $11.25/hour × 31.7 hours
Gross pay = $356.63
Rounding to the nearest cent gives us a final answer of $356.63. Therefore, the correct answer is choice C. We can calculate the gross pay by multiplying the number of hours by the hourly rate:
Gross pay = 31.7 hours * $11.25 per hour
Gross pay = $356.63 (rounded to the nearest cent)

Therefore, the best choice is C.

Question 6

Round the figure to the nearest dollar.
-$216.06

Accepted Answer

Rounding to the nearest dollar, the digit in the tens place (1) is less than 5, so we round down. Therefore, $216.06 rounded to the nearest dollar is $216. $216.06 is closer to $216 than $217, so rounding down to the nearest dollar gives $216.

-Lesley purchased office supplies for her business. She spent $5 on paper, $7 on pens, $8 on folders, and $92 on computer disks. What was the total amount that she spent?

Accepted Answer

Lesley's total expenditure is the sum of all her purchases: $5 + $7 + $8 + $92 = $112.

Question 10

Write the decimal using numbers.
-two and twelve thousandths

Accepted Answer

"Two" is 2 and "twelve thousandths" is expressed as 0.012. Therefore, the decimal would be 2.012. The number "two" represents the whole number 2, and "twelve thousandths" represents the decimal 0.012, so when combined, it becomes 2.012.

Question 11

Write the decimal using numbers.
-nine million, one hundred and nineteen ten-thousandths

Accepted Answer

The number is nine million (9,000,000) and one hundred and nineteen ten-thousandths (0.0019), combined as 9,000,000 + 0.0019 = 9,000,000.0019.

Question 12

Solve the problem.
-Jose Ramirez, a salesperson for a chemical company, travelled 1,539 miles on Monday, 407 miles on Tuesday, and 1,955 miles on Thursday. Find the total number of miles he travelled during these
Three days.

Accepted Answer

To find the total number of miles, we simply need to add the three distances together:

1,539 + 407 + 1,955 = 3,901

Therefore, the best choice is D, with a total of 3,901 miles travelled during these three days. To find the total number of miles travelled, we need to add up the distances travelled on each day. 
Total distance = 1,539 + 407 + 1,955
Total distance = 3,901 miles
Therefore, the answer is D) 3,901 mi.

Question 13

Perform the addition.
-

Accepted Answer

Since the problem involves hexadecimal addition, we need to convert all the hexadecimal digits to decimal before performing the addition. 
11ebb7d6 = 4,295,798,934 
6ebc_bfbf = 184,483,860,479 
ad4c_71b1_8326_c6ff = 308,647,055,421,735

TB8285 = 11,331,077

Performing the addition: 
4,295,798,934 + 184,483,860,479 + 308,647,055,421,735 + 11,331,077 = 308,835,589,102,225

Now we convert the sum to hexadecimal: 
308,835,589,102,225 in hexadecimal is d6e07e1cbf1, so choosing D is the correct answer.

Question 16

Round the number as requested.
-9,164 to the nearest thousand

Accepted Answer

To round 9,164 to the nearest thousand, we look at the hundreds place (6). Since 6 is greater than or equal to 5, we round up. The thousands digit (9) remains the same and the hundreds and tens digits become zeros. Therefore, 9,164 rounded to the nearest thousand is 9,000. To round 9,164 to the nearest thousand, we look at the digit in the hundreds place, which is 6. Since 6 is greater than or equal to 5, we must round up to the next thousand, which gives us 9,000. Therefore, the best choice is D.

Question 17

Solve the problem.
-Scrambled Electronics will finance a $235 TV set for $50 down and $38.32 a month for 6 months. How much money can you save by paying cash for the TV set?

Accepted Answer

The total cost of the TV set with financing is $50 down plus 6 months of $38.32, which is:

$50 + 6 x $38.32 = $50 + $229.92 = $279.92

If you pay cash for the TV, you only need to pay $235, so the amount of money you can save is:

$279.92 - $235 = $44.92

Therefore, the best choice is D, which corresponds to the amount of money you can save by paying cash. The total cost of financing the TV set is:
$50 (down payment) + $38.32/month for 6 months = $50 + $229.92 = $279.92

Therefore, if you pay cash for the TV set, you can save $279.92. Thus, the best choice is D.

Question 19

First use front-end rounding to write an estimate of the answer, and then multiply fully to obtain an exact answer.
-

Accepted Answer

Front-end rounding means rounding the first digit in a number to the nearest ten. In this case, the first digit is 1, so we round up to 2, making the estimate 120. When we multiply fully, we get 11.089, which is closest to the exact answer of 109.89. So, option C is the best choice. To use front-end rounding, we look at the first digit after the decimal point, which is 8. Since it is greater than or equal to 5, we round up the whole number to 110 instead of 109. Then, we drop the decimal point and multiply by 0.999: 
110 x 0.999 = 109.89 
Therefore, our estimate is 120 and our exact answer is 109.89. The only choice that matches is C.

Question 20

Express the number in words.
-4,700,345

Accepted Answer

The correct way to express the given number is to group the first three digits (4,700) as thousands and the last three digits (345) as hundreds, resulting in four million, seven hundred thousand, three hundred forty-five. Choice A is incorrect because it ignores the thousands grouping. Choice B is incorrect because it incorrectly separates the last three digits into two groups of three. Choice C is incorrect because it confuses the grouping of thousands and hundreds, placing 70,000 in the thousands place instead of 700,000.
