In a supermarket, 75% of the number of vegetables sold were carrots and the rest were potatoes. Each carrot cost 50¢ and each potato cost 20¢ less than the cost of each carrot. Given that $277.20 was collected from the sale of the vegetables,
- How many carrots were sold?
- How much was collected from the sale of the potatoes only?
(a)

Carrots |
Potatoes |
Number |
3 u |
1 u |
Value |
$0.50 |
$0.3 |
Total value |
1.5 u |
0.3 u |
75% =
75100 =
34Cost of each potato
= 0.50 - 0.20
= $0.3
Total cost of the vegetables
= 1.5 u + 0.3 u
= 1.8 u
1.8 u = 277.20
1 u = 277.20 ÷ 1.8 = 154
Number of carrots sold
= 3 u
= 3 x 154
= $462
(b)
Amount collected from the sale of potatoes
= 0.3 u
= 0.3 x 154
= $46.20
Answer(s): (a) 462; (b) $46.20
