In a supermarket, 75% of the number of vegetables sold were yams and the rest were ginger. Each yam cost 25¢ and each ginger cost 20¢ less than the cost of each yam. Given that $261.60 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 |
1 u |
Value |
$0.25 |
$0.05 |
Total value |
0.75 u |
0.05 u |
75% =
75100 =
34Cost of each ginger
= 0.25 - 0.20
= $0.05
Total cost of the vegetables
= 0.75 u + 0.05 u
= 0.8 u
0.8 u = 261.60
1 u = 261.60 ÷ 0.8 = 327
Number of yams sold
= 3 u
= 3 x 327
= $981
(b)
Amount collected from the sale of ginger
= 0.05 u
= 0.05 x 327
= $16.35
Answer(s): (a) 981; (b) $16.35
