Question 2

Solve the problem.
-Gina is buying a used car that has an advertised price of $3,500. She is buying the car on credit and must make a down payment of $900 and 30 monthly payments of $114. What is the total cost of the
Car?
A)$4,320
B)$4,206
C)$4,434
D)$3,614

Accepted Answer

The total cost of the car is the advertised price plus the down payment plus the total of the monthly payments. The total of the monthly payments is 30 x $114 = $3,420. So the total cost of the car is $3,500 + $900 + $3,420 = $7,820.

Question 6

Solve the problem.
-Carla's gross pay is $169 a week. $13 was withheld for federal income tax, $13 for FICA tax, and $6 for other deductions. How much of her pay is left?
A)$32
B)$201
C)$147
D)$137

Accepted Answer

Carla's total deductions are $13 + $13 + $6 = $32
Her net pay (what's left) is her gross pay minus deductions: $169 - $32 = $137

Question 7

Round the amount to the nearest cent.
-$56.59200
A)$56.60
B)$56.59
C)$56.589
D)$56.58

Accepted Answer

When rounding to the nearest cent, you look at the third decimal place. Since the third decimal place is 2, which is less than 5, you round down, keeping the second decimal place as 9. Thus, $56.59200 rounds to $56.59.

Question 10

Solve the problem.
-A country club wants to provide seating for 206 people in its banquet room. If the club has 19 tables that seat 6 people, how many tables does it need that seat 4 people?
A)25 tables
B)22 tables
C)23 tables
D)24 tables

Accepted Answer

The total number of people that can be seated at 6-person tables is:
19 tables x 6 people/table = 114 people

To find out how many 4-person tables are needed to seat the remaining people, subtract the number of people already seated from the total number of people who need seating:
206 people - 114 people = 92 people

To seat 92 people at 4-person tables, divide by the number of people per table:
92 people ÷ 4 people/table = 23 tables. The club already has 19 tables that seat 6 people which provide seating for 19*6 = 114 people. To seat the remaining 206-114 = 92 people, the club needs 92/4 = 23 tables that seat 4 people. Therefore, the total number of tables needed is 19+23 = 42, and the correct choice is C) 23 tables.

Question 11

Round the number to the nearest thousandth, nearest hundredth, and nearest tenth. Remember to round from the original
number.
-63.724
A)63.725, 63.73, 64
B)63.73, 63.8, 64
C)63.72, 63.7, 63
D)63.724, 63.72, 63.7

Accepted Answer

Rounding to the nearest thousandth does not change the number (63.724). Rounding to the nearest hundredth gives 63.72 (since the next digit, 4, is less than 5). Rounding to the nearest tenth gives 63.7 (since the next digit, 2, is less than 5).

Question 12

Round the amount to the nearest cent.
-$46.266
A)$46.27
B)$46.30
C)$46.26
D)$46.00

Accepted Answer

When rounding to the nearest cent, we look at the hundredths place. Since the digit in the hundredths place is 6 which is greater than or equal to 5, we round up the tenths place to 7. Therefore, the rounded amount is $46.27. To round to the nearest cent, we look at the digit in the third decimal place (which is 6 in this case). Since this digit is greater than or equal to 5, we round up the second decimal place (which is 6) to get $46.27.

Question 13

Solve the problem.
-Sales at Andrea's Formal Wear Shop were $877 this week. This is $183 less than the sales last week. What were last week's sales?
A)$694
B)$1,060
C)$1,049
D)$1,071

Accepted Answer

If this week's sales were $183 less than last week's sales, we can find last week's sales by adding $183 to this week's sales: $877 + $183 = $1,060. Therefore, the answer is choice B.

Question 14

Round the number as requested.
-627 to the nearest hundred
A)500
B)700
C)600
D)610

Accepted Answer

To round 627 to the nearest hundred, we need to look at the tens digit which is 2. If the tens digit is 5 or greater, we round up; if it's 4 or less, we round down. Since the tens digit is less than 5, we round down, and the hundreds digit remains 6. Therefore, the rounded number is 600. So, the best choice is C. In order to round 627 to the nearest hundred, we need to look at the tens digit, which is 2. Since 2 is less than 5, we round down to 600. Therefore, the best choice is C.

Question 17

Solve the problem.
-The city bridge has 7 lanes, all carrying equal numbers of cars. If 385 cars drive across the bridge, how many cars cross in each lane?
A)56 cars
B)62 cars
C)55 cars
D)392 cars

Accepted Answer

If all 7 lanes carry equal numbers of cars, then we need to divide 385 by 7 to find out how many cars cross in each lane. 
385 ÷ 7 = 55, so each lane carries 55 cars. Therefore, the correct answer is choice C. To find out how many cars cross in each lane, we need to divide the total number of cars by the number of lanes:
385 cars ÷ 7 lanes = 55 cars per lane. Therefore, the best choice is (C) 55 cars.

Question 18

Write the decimal in words.
-8.00606
A)eight and sixty-six hundred-thousandths
B)eight and six hundred six ten-thousandths
C)eight and six hundred six hundred-thousandths
D)eight and sixty thousand six hundredths

Accepted Answer

The number 8.00606 is read as "eight and six hundred six hundred-thousandths" because the digits after the decimal point represent hundred-thousandths.

Question 20

Perform the indicated operation.
-2.21 ÷ 0.074 (Round to the nearest hundredths when necessary.)
A)2.99
B)3.04
C)29.86
D)30.36

Accepted Answer

To divide 2.21 by 0.074, we can use long division or a calculator. Using a calculator, we get 29.86486486... Rounded to the nearest hundredths, the answer is 29.86. Therefore, the best choice is C. To divide the given numbers, we need to move the decimal point of the divisor (0.074) to the right until it becomes a whole number.

0.074 × 1000 = 74

Now we can proceed with the division:

2.21 ÷ 74 = 0.02986

Rounding to the nearest hundredths, we get:

0.02986 ≈ 0.03

Therefore, the answer is 29.86, which is choice C.
