In a supermarket, 70% of the number of vegetables sold were radishes and the rest were potatoes. Each radish cost 25¢ and each potato cost 20¢ less than the cost of each radish. Given that $178.60 was collected from the sale of the vegetables,
- How many radishes were sold?
- How much was collected from the sale of the potatoes only?
(a)

Radishes |
Potatoes |
Number |
7 u |
3 u |
Value |
$0.25 |
$0.05 |
Total value |
1.75 u |
0.15 u |
70% =
70100 =
710Cost of each potato
= 0.25 - 0.20
= $0.05
Total cost of the vegetables
= 1.75 u + 0.15 u
= 1.9 u
1.9 u = 178.60
1 u = 178.60 ÷ 1.9 = 94
Number of radishes sold
= 7 u
= 7 x 94
= $658
(b)
Amount collected from the sale of potatoes
= 0.15 u
= 0.15 x 94
= $14.10
Answer(s): (a) 658; (b) $14.10
