In a kiosk, 75% of the number of vegetables sold were onions and the rest were garlics. Each onion cost 25¢ and each garlic cost 20¢ less than the cost of each onion. Given that $246.40 was collected from the sale of the vegetables,
- How many onions were sold?
- How much was collected from the sale of the garlics only?
(a)
|
Onions |
Garlics |
Number |
3 u |
1 u |
Value |
$0.25 |
$0.05 |
Total value |
0.75 u |
0.05 u |
75% =
75100 =
34Cost of each garlic
= 0.25 - 0.20
= $0.05
Total cost of the vegetables
= 0.75 u + 0.05 u
= 0.8 u
0.8 u = 246.40
1 u = 246.40 ÷ 0.8 = 308
Number of onions sold
= 3 u
= 3 x 308
= $924
(b)
Amount collected from the sale of garlics
= 0.05 u
= 0.05 x 308
= $15.40
Answer(s): (a) 924; (b) $15.40
