In a supermarket, 60% of the number of vegetables sold were radishes and the rest were yams. Each radish cost 25¢ and each yam cost 20¢ less than the cost of each radish. Given that $215.90 was collected from the sale of the vegetables,
- How many radishes were sold?
- How much was collected from the sale of the yams only?
(a)
|
Radishes |
Yams |
Number |
3 u |
2 u |
Value |
$0.25 |
$0.05 |
Total value |
0.75 u |
0.1 u |
60% =
60100 =
35Cost of each yam
= 0.25 - 0.20
= $0.05
Total cost of the vegetables
= 0.75 u + 0.1 u
= 0.85 u
0.85 u = 215.90
1 u = 215.90 ÷ 0.85 = 254
Number of radishes sold
= 3 u
= 3 x 254
= $762
(b)
Amount collected from the sale of yams
= 0.1 u
= 0.1 x 254
= $25.40
Answer(s): (a) 762; (b) $25.40
