Rasheed wants to buy two new video games that cost $28.50 each. He earns money for them by mowing lawns in his neighborhood, and his earnings are shown in the table below. Rasheed’s EarningsWeekAmount Earned1$7.502$4.853$12.254$9.005$8.15How much more does Rasheed need to earn before he can buy the video games?

Answer

A

$3.85

B

$13.25

C

$15.25

D

$17.00

Explanation

The two games cost 2 × $28.50 = $57.00 altogether. Rasheed has earned $7.50 + $4.85 + $12.25 + $9.00 + $8.15 = $41.75. Subtracting his earnings from the total cost gives $57.00 − $41.75 = $15.25, so he needs $15.25 more (choice C).
