In a shop, 60% of the number of vegetables sold were onions and the rest were carrots. Each onion cost 25¢ and each carrot cost 10¢ less than the cost of each onion. Given that $176.40 was collected from the sale of the vegetables,
- How many onions were sold?
- How much was collected from the sale of the carrots only?
(a)
|
Onions |
Carrots |
Number |
3 u |
2 u |
Value |
$0.25 |
$0.15 |
Total value |
0.75 u |
0.3 u |
60% =
60100 =
35Cost of each carrot
= 0.25 - 0.10
= $0.15
Total cost of the vegetables
= 0.75 u + 0.3 u
= 1.05 u
1.05 u = 176.40
1 u = 176.40 ÷ 1.05 = 168
Number of onions sold
= 3 u
= 3 x 168
= $504
(b)
Amount collected from the sale of carrots
= 0.3 u
= 0.3 x 168
= $50.40
Answer(s): (a) 504; (b) $50.40
