In a stall, 60% of the number of vegetables sold were garlics and the rest were carrots. Each garlic cost 50¢ and each carrot cost 20¢ less than the cost of each garlic. Given that $176.40 was collected from the sale of the vegetables,
- How many garlics were sold?
- How much was collected from the sale of the carrots only?
(a)
|
Garlics |
Carrots |
Number |
3 u |
2 u |
Value |
$0.50 |
$0.3 |
Total value |
1.5 u |
0.6 u |
60% =
60100 =
35Cost of each carrot
= 0.50 - 0.20
= $0.3
Total cost of the vegetables
= 1.5 u + 0.6 u
= 2.1 u
2.1 u = 176.40
1 u = 176.40 ÷ 2.1 = 84
Number of garlics sold
= 3 u
= 3 x 84
= $252
(b)
Amount collected from the sale of carrots
= 0.6 u
= 0.6 x 84
= $50.40
Answer(s): (a) 252; (b) $50.40
