In a stall, 70% of the number of vegetables sold were sweet potatoes and the rest were turnips. Each sweet potato cost 50¢ and each turnip cost 10¢ less than the cost of each sweet potato. Given that $192.70 was collected from the sale of the vegetables,
- How many sweet potatoes were sold?
- How much was collected from the sale of the turnips only?

Sweet Potatoes |
Turnips |

3 u |
Value |
$0.50 |
$0.4 |
Total value |
3.5 u |
1.2 u |
70% =
70100 =
710Cost of each turnip
= 0.50 - 0.10
= $0.4
Total cost of the vegetables
= 3.5 u + 1.2 u
= 4.7 u
4.7 u = 192.70
1 u = 192.70 ÷ 4.7 = 41
Number of sweet potatoes sold
= 7 u
= 7 x 41
= $287
(b)
Amount collected from the sale of turnips
= 1.2 u
= 1.2 x 41
= $49.20
Answer(s): (a) 287; (b) $49.20
