In a supermarket, 75% of the number of vegetables sold were yams and the rest were beets. Each yam cost 50¢ and each beet cost 20¢ less than the cost of each yam. Given that $217.80 was collected from the sale of the vegetables,
- How many yams were sold?
- How much was collected from the sale of the beets only?
(a)
|
Yams |
Beets |
Number |
3 u |
1 u |
Value |
$0.50 |
$0.3 |
Total value |
1.5 u |
0.3 u |
75% =
75100 =
34Cost of each beet
= 0.50 - 0.20
= $0.3
Total cost of the vegetables
= 1.5 u + 0.3 u
= 1.8 u
1.8 u = 217.80
1 u = 217.80 ÷ 1.8 = 121
Number of yams sold
= 3 u
= 3 x 121
= $363
(b)
Amount collected from the sale of beets
= 0.3 u
= 0.3 x 121
= $36.30
Answer(s): (a) 363; (b) $36.30
