In a stall, 70% of the number of vegetables sold were potatoes and the rest were garlics. Each potato cost 25¢ and each garlic cost 20¢ less than the cost of each potato. Given that $212.80 was collected from the sale of the vegetables,
- How many potatoes were sold?
- How much was collected from the sale of the garlics only?

Potatoes |

$0.05 |
Total value |
1.75 u |
0.15 u |
70% =
70100 =
710Cost of each garlic
= 0.25 - 0.20
= $0.05
Total cost of the vegetables
= 1.75 u + 0.15 u
= 1.9 u
1.9 u = 212.80
1 u = 212.80 ÷ 1.9 = 112
Number of potatoes sold
= 7 u
= 7 x 112
= $784
(b)
Amount collected from the sale of garlics
= 0.15 u
= 0.15 x 112
= $16.80
Answer(s): (a) 784; (b) $16.80
