Lui bought 8
r boxes of mangosteens. Each box had 20 mangosteens. He gave away 70 mangosteens to his mother.
- How many mangosteens had he left?
- If he sold the rest at 41¢ each and r = 8, how much money did he receive from the mangosteens sold? Give your answer in dollars.
(a)
Total number of mangosteens
= 20 x 8
r = 160
r Number of mangosteens left
= 160
r - 70
(b)
Total mangosteens left
= 160
r - 70
= (160 x 8) - 70
= 1280 - 70
= 1210
Total amount received from the sale
= 1210 x 41
= 49610¢
$1 = 100¢
49610¢ = 49610 ÷ 100 = $496.10
Answer(s): (a) 160
r - 70; (b) $496.10
