John bought 4
j boxes of starfruits. Each box had 25 starfruits. He gave away 70 starfruits to his neighbour.
- How many starfruits had he left?
- If he sold the rest at 45¢ each and j = 8, how much money did he receive from the starfruits sold? Give your answer in dollars.
(a)
Total number of starfruits
= 25 x 4
j = 100
j Number of starfruits left
= 100
j - 70
(b)
Total starfruits left
= 100
j - 70
= (100 x 8) - 70
= 800 - 70
= 730
Total amount received from the sale
= 730 x 45
= 32850¢
$1 = 100¢
32850¢ = 32850 ÷ 100 = $328.50
Answer(s): (a) 100
j - 70; (b) $328.50
