In a supermarket, 75% of the number of vegetables sold were ginger and the rest were radishes. Each ginger cost 25¢ and each radish cost 20¢ less than the cost of each ginger. Given that $191.20 was collected from the sale of the vegetables,
- How many ginger were sold?
- How much was collected from the sale of the radishes only?

$0.05 |
Total value |
0.75 u |
0.05 u |
75% =
75100 =
34Cost of each radish
= 0.25 - 0.20
= $0.05
Total cost of the vegetables
= 0.75 u + 0.05 u
= 0.8 u
0.8 u = 191.20
1 u = 191.20 ÷ 0.8 = 239
Number of ginger sold
= 3 u
= 3 x 239
= $717
(b)
Amount collected from the sale of radishes
= 0.05 u
= 0.05 x 239
= $11.95
Answer(s): (a) 717; (b) $11.95
