In a shop, 70% of the number of vegetables sold were potatoes and the rest were garlics. Each potato cost 25¢ and each garlic cost 10¢ less than the cost of each potato. Given that $215.60 was collected from the sale of the vegetables,
- How many potatoes were sold?
- How much was collected from the sale of the garlics only?
(a)
|
Potatoes |
Garlics |
Number |
7 u |
3 u |
Value |
$0.25 |
$0.15 |
Total value |
1.75 u |
0.45 u |
70% =
70100 =
710Cost of each garlic
= 0.25 - 0.10
= $0.15
Total cost of the vegetables
= 1.75 u + 0.45 u
= 2.2 u
2.2 u = 215.60
1 u = 215.60 ÷ 2.2 = 98
Number of potatoes sold
= 7 u
= 7 x 98
= $686
(b)
Amount collected from the sale of garlics
= 0.45 u
= 0.45 x 98
= $44.10
Answer(s): (a) 686; (b) $44.10
