John bought 5
b boxes of starfruits. Each box had 40 starfruits. He gave away 70 starfruits to his nephew.
- How many starfruits had he left?
- If he sold the rest at 47¢ each and b = 8, how much money did he receive from the starfruits sold? Give your answer in dollars.
(a)
Total number of starfruits
= 40 x 5
b = 200
b Number of starfruits left
= 200
b - 70
(b)
Total starfruits left
= 200
b - 70
= (200 x 8) - 70
= 1600 - 70
= 1530
Total amount received from the sale
= 1530 x 47
= 71910¢
$1 = 100¢
71910¢ = 71910 ÷ 100 = $719.10
Answer(s): (a) 200
b - 70; (b) $719.10
