In a shop, 60% of the number of vegetables sold were carrots and the rest were garlics. Each carrot cost 25¢ and each garlic cost 20¢ less than the cost of each carrot. Given that $176.80 was collected from the sale of the vegetables,
- How many carrots were sold?
- How much was collected from the sale of the garlics only?
(a)
|
Carrots |
Garlics |
Number |
3 u |
2 u |
Value |
$0.25 |
$0.05 |
Total value |
0.75 u |
0.1 u |
60% =
60100 =
35Cost of each garlic
= 0.25 - 0.20
= $0.05
Total cost of the vegetables
= 0.75 u + 0.1 u
= 0.85 u
0.85 u = 176.80
1 u = 176.80 ÷ 0.85 = 208
Number of carrots sold
= 3 u
= 3 x 208
= $624
(b)
Amount collected from the sale of garlics
= 0.1 u
= 0.1 x 208
= $20.80
Answer(s): (a) 624; (b) $20.80
