In a supermarket, 75% of the number of vegetables sold were radishes and the rest were yams. Each radish cost 25¢ and each yam cost 10¢ less than the cost of each radish. Given that $234.90 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 |
1 u |
Value |
$0.25 |
$0.15 |
Total value |
0.75 u |
0.15 u |
75% =
75100 =
34Cost of each yam
= 0.25 - 0.10
= $0.15
Total cost of the vegetables
= 0.75 u + 0.15 u
= 0.9 u
0.9 u = 234.90
1 u = 234.90 ÷ 0.9 = 261
Number of radishes sold
= 3 u
= 3 x 261
= $783
(b)
Amount collected from the sale of yams
= 0.15 u
= 0.15 x 261
= $39.15
Answer(s): (a) 783; (b) $39.15
