In a supermarket, 55% of the number of vegetables sold were carrots and the rest were yams. Each carrot cost 50¢ and each yam cost 20¢ less than the cost of each carrot. Given that $196.80 was collected from the sale of the vegetables,
- How many carrots were sold?
- How much was collected from the sale of the yams only?
(a)
|
Carrots |
Yams |
Number |
11 u |
9 u |
Value |
$0.50 |
$0.3 |
Total value |
5.5 u |
2.7 u |
55% =
55100 =
1120Cost of each yam
= 0.50 - 0.20
= $0.3
Total cost of the vegetables
= 5.5 u + 2.7 u
= 8.2 u
8.2 u = 196.80
1 u = 196.80 ÷ 8.2 = 24
Number of carrots sold
= 11 u
= 11 x 24
= $264
(b)
Amount collected from the sale of yams
= 2.7 u
= 2.7 x 24
= $64.80
Answer(s): (a) 264; (b) $64.80
