In a stall, 60% of the number of vegetables sold were carrots and the rest were ginger. Each carrot cost 50¢ and each ginger cost 20¢ less than the cost of each carrot. Given that $249.90 was collected from the sale of the vegetables,
- How many carrots were sold?
- How much was collected from the sale of the ginger only?
(a)
|

Ginger |
Number |
3 u |
2 u |
Value |
$0.50 |
$0.3 |
Total value |
1.5 u |
0.6 u |
60% =
60100 =
35Cost of each ginger
= 0.50 - 0.20
= $0.3
Total cost of the vegetables
= 1.5 u + 0.6 u
= 2.1 u
2.1 u = 249.90
1 u = 249.90 ÷ 2.1 = 119
Number of carrots sold
= 3 u
= 3 x 119
= $357
(b)
Amount collected from the sale of ginger
= 0.6 u
= 0.6 x 119
= $71.40
Answer(s): (a) 357; (b) $71.40
