In a kiosk, 70% of the number of vegetables sold were potatoes and the rest were turnips. Each potato cost 25¢ and each turnip cost 10¢ less than the cost of each potato. Given that $270.60 was collected from the sale of the vegetables,
- How many potatoes were sold?
- How much was collected from the sale of the turnips only?
(a)

Potatoes |
Turnips |
Number |
7 u |
3 u |
Value |

$0.15 |
Total value |
1.75 u |
0.45 u |
70% =
70100 =
710Cost of each turnip
= 0.25 - 0.10
= $0.15
Total cost of the vegetables
= 1.75 u + 0.45 u
= 2.2 u
2.2 u = 270.60
1 u = 270.60 ÷ 2.2 = 123
Number of potatoes sold
= 7 u
= 7 x 123
= $861
(b)
Amount collected from the sale of turnips
= 0.45 u
= 0.45 x 123
= $55.35
Answer(s): (a) 861; (b) $55.35
