In a stall, 75% of the number of vegetables sold were yams and the rest were ginger. Each yam cost 50¢ and each ginger cost 20¢ less than the cost of each yam. Given that $275.40 was collected from the sale of the vegetables,
- How many yams were sold?
- How much was collected from the sale of the ginger only?
(a)
|

75% =
75100 =
34Cost of each ginger
= 0.50 - 0.20
= $0.3
Total cost of the vegetables
= 1.5 u + 0.3 u
= 1.8 u
1.8 u = 275.40
1 u = 275.40 ÷ 1.8 = 153
Number of yams sold
= 3 u
= 3 x 153
= $459
(b)
Amount collected from the sale of ginger
= 0.3 u
= 0.3 x 153
= $45.90
Answer(s): (a) 459; (b) $45.90
