Question 1

If you invest $10,000 at an annual rate of 7%, how much interest will you earn after one year?

Accepted Answer

$700

Answer

To calculate the interest earned, use the simple interest formula: Interest = Principal × Rate × Time. The principal is $10,000, the annual rate is 7% (or 0.07 as a decimal), and the time is 1 year. Multiplying these values ($10,000 × 0.07 × 1) yields an interest of $700.

Question 2

Four tons of gravel weighs how many pounds?

Accepted Answer

8000

Answer

To convert tons to pounds, you need to know the conversion factor: 1 ton is equal to 2000 pounds. Therefore, to find the weight of four tons of gravel in pounds, multiply 4 by 2000. This calculation results in 8000 pounds.

Question 3

If the price of a gallon of gas increases from $3.20 to $3.68, what percent did it increase?

Accepted Answer

15%

Answer

First, calculate the amount of the price increase: $3.68 - $3.20 = $0.48. To find the percent increase, divide the increase amount by the original price and then multiply by 100. So, ($0.48 / $3.20) × 100% = 0.15 × 100% = 15%.

Question 4

If 5 apples cost $2.00, how much will 15 apples cost?

Accepted Answer

$6

Answer

You can solve this using a proportion or by finding the unit price. If 5 apples cost $2.00, then each apple costs $2.00 / 5 = $0.40. To find the cost of 15 apples, multiply the unit price by 15: $0.40 × 15 = $6.00.

Question 5

If 4 people can stain a deck in 2 days, how many people would be required to stain the deck in only 1 day?

Accepted Answer

8

Answer

This is an inverse proportion problem, meaning as the number of days decreases, the number of people required increases. The total amount of work is constant: 4 people × 2 days = 8 'person-days' of work. To complete this same amount of work in 1 day, you would need 8 'person-days' / 1 day = 8 people.
