In a supermarket, 60% of the number of vegetables sold were ginger and the rest were beets. Each ginger cost 50¢ and each beet cost 10¢ less than the cost of each ginger. Given that $190.90 was collected from the sale of the vegetables,
- How many ginger were sold?
- How much was collected from the sale of the beets only?
(a)
|
Ginger |
Beets |
Number |
3 u |
2 u |
Value |
$0.50 |
$0.4 |
Total value |
1.5 u |
0.8 u |
60% =
60100 =
35Cost of each beet
= 0.50 - 0.10
= $0.4
Total cost of the vegetables
= 1.5 u + 0.8 u
= 2.3 u
2.3 u = 190.90
1 u = 190.90 ÷ 2.3 = 83
Number of ginger sold
= 3 u
= 3 x 83
= $249
(b)
Amount collected from the sale of beets
= 0.8 u
= 0.8 x 83
= $66.40
Answer(s): (a) 249; (b) $66.40
