In a shop, 70% of the number of vegetables sold were ginger and the rest were potatoes. Each ginger cost 50¢ and each potato cost 10¢ less than the cost of each ginger. Given that $216.20 was collected from the sale of the vegetables,
- How many ginger were sold?
- How much was collected from the sale of the potatoes only?
(a)
|
Ginger |
Potatoes |
Number |
7 u |
3 u |
Value |
$0.50 |
$0.4 |
Total value |
3.5 u |
1.2 u |
70% =
70100 =
710Cost of each potato
= 0.50 - 0.10
= $0.4
Total cost of the vegetables
= 3.5 u + 1.2 u
= 4.7 u
4.7 u = 216.20
1 u = 216.20 ÷ 4.7 = 46
Number of ginger sold
= 7 u
= 7 x 46
= $322
(b)
Amount collected from the sale of potatoes
= 1.2 u
= 1.2 x 46
= $55.20
Answer(s): (a) 322; (b) $55.20
