In a supermarket, 70% of the number of vegetables sold were radishes and the rest were garlics. Each radish cost 50¢ and each garlic cost 20¢ less than the cost of each radish. Given that $224.40 was collected from the sale of the vegetables,
- How many radishes were sold?
- How much was collected from the sale of the garlics only?
(a)
|
Radishes |
Garlics |
Number |
7 u |
3 u |
Value |
$0.50 |
$0.3 |
Total value |
3.5 u |
0.9 u |
70% =
70100 =
710Cost of each garlic
= 0.50 - 0.20
= $0.3
Total cost of the vegetables
= 3.5 u + 0.9 u
= 4.4 u
4.4 u = 224.40
1 u = 224.40 ÷ 4.4 = 51
Number of radishes sold
= 7 u
= 7 x 51
= $357
(b)
Amount collected from the sale of garlics
= 0.9 u
= 0.9 x 51
= $45.90
Answer(s): (a) 357; (b) $45.90
