In a supermarket, 65% of the number of vegetables sold were ginger and the rest were onions. Each ginger cost 25¢ and each onion cost 10¢ less than the cost of each ginger. Given that $279.50 was collected from the sale of the vegetables,
- How many ginger were sold?
- How much was collected from the sale of the onions only?
(a)
|
Ginger |
Onions |
Number |
13 u |
7 u |
Value |
$0.25 |
$0.15 |
Total value |
3.25 u |
1.05 u |
65% =
65100 =
1320Cost of each onion
= 0.25 - 0.10
= $0.15
Total cost of the vegetables
= 3.25 u + 1.05 u
= 4.3 u
4.3 u = 279.50
1 u = 279.50 ÷ 4.3 = 65
Number of ginger sold
= 13 u
= 13 x 65
= $845
(b)
Amount collected from the sale of onions
= 1.05 u
= 1.05 x 65
= $68.25
Answer(s): (a) 845; (b) $68.25
