In a kiosk, 60% of the number of vegetables sold were potatoes and the rest were yams. Each potato cost 50¢ and each yam cost 10¢ less than the cost of each potato. Given that $211.60 was collected from the sale of the vegetables,
- How many potatoes were sold?
- How much was collected from the sale of the yams only?
(a)
|
Potatoes |
Yams |
Number |
3 u |
2 u |
Value |
$0.50 |
$0.4 |
Total value |
1.5 u |
0.8 u |
60% =
60100 =
35Cost of each yam
= 0.50 - 0.10
= $0.4
Total cost of the vegetables
= 1.5 u + 0.8 u
= 2.3 u
2.3 u = 211.60
1 u = 211.60 ÷ 2.3 = 92
Number of potatoes sold
= 3 u
= 3 x 92
= $276
(b)
Amount collected from the sale of yams
= 0.8 u
= 0.8 x 92
= $73.60
Answer(s): (a) 276; (b) $73.60
