### Rich moved some of his money from his savings account to his checking account to cover the cost of his new car. Rich's savings account originally had \$89,848.62 in it, and now his balance is \$59,998.62. Estimate how much money did Rich spend on his new car?

\$40,000

\$30,000

\$25,000

\$10,000

The difference between approximately \$90,000 and \$60,000 is \$30,000. Approximations are used to save time when a precise figure isn't necessary practical.

### How many minutes are there in five days?

1,440 minutes

2,400 minutes

7,200 minutes

6,000minutes

In order to solve the problem, convert the units from days to hours. 1 day = 24 hours 1 day x 5 = 24 hours x 5 = 120 hours Next convert hours to minutes. 1 hour = 60 minutes 1 hour x 120 = 60 minutes x 120 = 7,200 minutes

### Ashley was 98 pounds one year ago. If she now weighs 112 pounds, what is the percent increase in her weight?

15.3%

18.5%

12.5%

14.2%

Ashley's weight changed by 112 - 98, or 14 pounds. Divide this amount by the original amount and multiply by 100 to determine percent change. (14 \u00F7 98) \u00D7 100 = 14.2%

### In her will, Laura left 20% of her estate to her niece, 25% to her daughter, and the remaining portion to one of her favorite charities. If the daughter received \$20,000 as her share, what was the total amount of money given to charity?

\$44,000

\$40,000

\$54,000

Not enough information given

Laura gave 25% of her estate, or \$20,000, to her daughter. We can find the total value of the estate by setting up an equation: .25x = 20,000 x = \$80,000\u00A0 Next, we need to find out the percentage of Laura's total estate that was given to the charity. 20 + 25 + y = 100 45 + y = 100 y = 55\u00A0 55% of Laura's estate was give the to the charity. Since we know the total value of the estate is \$80,000, we multiply that by 55%. 80,000 x .55 = 44,000 Laura gave \$44,000 to her favorite charity.

### Mark orders five pizzas to feed 10 people. Each pizza has 8 slices. How many slices will each person be able to eat if it is divided evenly among them?

3

5

6

4

First, calculate the total number of slices: 5 pizzas × 8 slices per pizza = 40 slices Next, calculate how many slices per person: 40 slices ÷ 10 people = 4 slices per person

### A box is 5 inches high, 10 inches wide, and 8 inches deep. What is the volume of the box?

189 cubic inches

800 cubic inches

400 cubic inches

80 cubic inches

The formula to find the volume of a box is height x width x depth. Thus, the volume of the box is 5 x 10 x 8 = 400 cubic inches.

### Express 21 as a percentage of 57.

11.97%

0.36%

36.84%

25.78%

To express one number as a percentage of another number, calculate its decimal value and multiply it by a 100: (21 ÷ 57) × 100 (0.3684) × 100 = 36.84%

### The chef used 2 tablespoons of salt, 4 tablespoons of baking soda, and some pepper. There is a 1 to 3 ratio of salt to pepper. Which of the following numbers in the problem are needed to find the total number of tablespoons of pepper that the chef will use?

4, 1, and 3 only

4, 2, 1, and 3

1 and 3 only

2, 1, and 3 only

In order to find the actual number of tablespoons of pepper, you need the initial ratio, plus one actual number. The initial ratio of salt to pepper is 1 to 3, and the actual number of tablespoons of salt is 2. You do not need the fact that the chef used 4 tablespoons of baking soda. This piece of information does nothing to help you solve the ratio involving salt and pepper.
