Question 1

A store sells notebooks for $3.75 each and pens for $1.25 each. Maria buys 4 notebooks and 6 pens. If she pays with a $25 bill, how much change does she receive?

Accepted Answer

$2.50

Answer

4 × $3.75 = $15.00 and 6 × $1.25 = $7.50, so total = $22.50 and change = $25.00 − $22.50 = $2.50.

Question 2

A recipe calls for 2¼ cups of flour per batch. If Tyler wants to make 3 batches but already has 2 cups of flour, how many more cups does he need?

Accepted Answer

4¾ cups

Answer

Total needed = 3 × 2¼ = 6¾ cups; subtract the 2 cups on hand gives 6¾ − 2 = 4¾ cups.

Question 3

A pool holds 12,000 gallons. It is currently 35% full. A pump adds 150 gallons per hour. How many hours will it take to fill the pool to 80% capacity?

Accepted Answer

36 hours

Answer

80% of 12,000 = 9,600 gal; 35% = 4,200 gal already in pool; need 5,400 more gal ÷ 150 gal/hr = 36 hours.

Question 4

Sarah earns $12 per hour and works 8 hours on weekdays and 10 hours on weekends. In one week (5 weekdays, 2 weekend days), how much does she earn in total?

Accepted Answer

$720

Answer

Weekday earnings = 5 × 8 × $12 = $480; weekend earnings = 2 × 10 × $12 = $240; total = $720.

Question 5

A car travels 240 miles on 8 gallons of gas. At this rate, how far can it travel on 5 gallons?

Accepted Answer

150 miles

Answer

The car gets 240 ÷ 8 = 30 mpg, so on 5 gallons it travels 5 × 30 = 150 miles.
