In a stall, 70% of the number of vegetables sold were garlics and the rest were onions. Each garlic cost 50¢ and each onion cost 10¢ less than the cost of each garlic. Given that $230.30 was collected from the sale of the vegetables,
- How many garlics were sold?
- How much was collected from the sale of the onions only?

Garlics |
Onions |
Number |
7 u |
3 u |
Value |
$0.50 |
$0.4 |
Total value |
3.5 u |
1.2 u |
70% =
70100 =
710Cost of each onion
= 0.50 - 0.10
= $0.4
Total cost of the vegetables
= 3.5 u + 1.2 u
= 4.7 u
4.7 u = 230.30
1 u = 230.30 ÷ 4.7 = 49
Number of garlics sold
= 7 u
= 7 x 49
= $343
(b)
Amount collected from the sale of onions
= 1.2 u
= 1.2 x 49
= $58.80
Answer(s): (a) 343; (b) $58.80
