In a stall, 55% of the number of vegetables sold were carrots and the rest were onions. Each carrot cost 25¢ and each onion cost 20¢ less than the cost of each carrot. Given that $278.40 was collected from the sale of the vegetables,
- How many carrots were sold?
- How much was collected from the sale of the onions only?

$0.05 |
Total value |
2.75 u |
0.45 u |
55% =
55100 =
1120Cost of each onion
= 0.25 - 0.20
= $0.05
Total cost of the vegetables
= 2.75 u + 0.45 u
= 3.2 u
3.2 u = 278.40
1 u = 278.40 ÷ 3.2 = 87
Number of carrots sold
= 11 u
= 11 x 87
= $957
(b)
Amount collected from the sale of onions
= 0.45 u
= 0.45 x 87
= $39.15
Answer(s): (a) 957; (b) $39.15
