Perry bought 9
y containers of grapefruits. Each container had 31 grapefruits. He gave away 72 grapefruits to his neighbour.
- How many grapefruits had he left?
- If he sold the rest at 43¢ each and y = 8, how much money did he receive from the grapefruits sold? Give your answer in dollars.
(a)
Total number of grapefruits
= 31 x 9
y = 279
y Number of grapefruits left
= 279
y - 72
(b)
Total grapefruits left
= 279
y - 72
= (279 x 8) - 72
= 2232 - 72
= 2160
Total amount received from the sale
= 2160 x 43
= 92880¢
$1 = 100¢
92880¢ = 92880 ÷ 100 = $928.80
Answer(s): (a) 279
y - 72; (b) $928.80
