In a kiosk, 70% 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 $243.20 was collected from the sale of the vegetables,
- How many ginger were sold?
- How much was collected from the sale of the radishes only?

70% =
70100 =
710Cost of each radish
= 0.25 - 0.20
= $0.05
Total cost of the vegetables
= 1.75 u + 0.15 u
= 1.9 u
1.9 u = 243.20
1 u = 243.20 ÷ 1.9 = 128
Number of ginger sold
= 7 u
= 7 x 128
= $896
(b)
Amount collected from the sale of radishes
= 0.15 u
= 0.15 x 128
= $19.20
Answer(s): (a) 896; (b) $19.20
