In a supermarket, 60% of the number of vegetables sold were yams and the rest were ginger. Each yam cost 50¢ and each ginger cost 10¢ less than the cost of each yam. Given that $262.20 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)
|
Yams |
Ginger |
Number |
3 u |
2 u |
Value |
$0.50 |
$0.4 |
Total value |
1.5 u |
0.8 u |
60% =
60100 =
35Cost of each ginger
= 0.50 - 0.10
= $0.4
Total cost of the vegetables
= 1.5 u + 0.8 u
= 2.3 u
2.3 u = 262.20
1 u = 262.20 ÷ 2.3 = 114
Number of yams sold
= 3 u
= 3 x 114
= $342
(b)
Amount collected from the sale of ginger
= 0.8 u
= 0.8 x 114
= $91.20
Answer(s): (a) 342; (b) $91.20
