In a shop, 70% of the number of vegetables sold were garlics and the rest were yams. Each garlic cost 25¢ and each yam cost 10¢ less than the cost of each garlic. Given that $184.80 was collected from the sale of the vegetables,
- How many garlics were sold?
- How much was collected from the sale of the yams only?
(a)

Garlics |
Yams |
Number |
7 u |
3 u |
Value |
$0.25 |
$0.15 |
Total value |
1.75 u |
0.45 u |
70% =
70100 =
710Cost of each yam
= 0.25 - 0.10
= $0.15
Total cost of the vegetables
= 1.75 u + 0.45 u
= 2.2 u
2.2 u = 184.80
1 u = 184.80 ÷ 2.2 = 84
Number of garlics sold
= 7 u
= 7 x 84
= $588
(b)
Amount collected from the sale of yams
= 0.45 u
= 0.45 x 84
= $37.80
Answer(s): (a) 588; (b) $37.80
