In a kiosk, 70% of the number of vegetables sold were yams and the rest were radishes. Each yam cost 50¢ and each radish cost 10¢ less than the cost of each yam. Given that $225.60 was collected from the sale of the vegetables,
- How many yams were sold?
- How much was collected from the sale of the radishes only?
(a)
|
Yams |
Radishes |
Number |
7 u |
3 u |
Value |
$0.50 |
$0.4 |
Total value |
3.5 u |
1.2 u |
70% =
70100 =
710Cost of each radish
= 0.50 - 0.10
= $0.4
Total cost of the vegetables
= 3.5 u + 1.2 u
= 4.7 u
4.7 u = 225.60
1 u = 225.60 ÷ 4.7 = 48
Number of yams sold
= 7 u
= 7 x 48
= $336
(b)
Amount collected from the sale of radishes
= 1.2 u
= 1.2 x 48
= $57.60
Answer(s): (a) 336; (b) $57.60
