Brandon bought 9
x boxes of grapefruits. Each box had 31 grapefruits. He gave away 72 grapefruits to his auntie.
- How many grapefruits had he left?
- If he sold the rest at 47¢ each and x = 8, how much money did he receive from the grapefruits sold? Give your answer in dollars.
(a)
Total number of grapefruits
= 31 x 9
x = 279
x Number of grapefruits left
= 279
x - 72
(b)
Total grapefruits left
= 279
x - 72
= (279 x 8) - 72
= 2232 - 72
= 2160
Total amount received from the sale
= 2160 x 47
= 101520¢
$1 = 100¢
101520¢ = 101520 ÷ 100 = $1015.20
Answer(s): (a) 279
x - 72; (b) $1015.20
