In a shop, 65% of the number of vegetables sold were yams and the rest were potatoes. Each yam cost 25¢ and each potato cost 20¢ less than the cost of each yam. Given that $273.60 was collected from the sale of the vegetables,
- How many yams were sold?
- How much was collected from the sale of the potatoes only?
(a)
|
Yams |
Potatoes |
Number |
13 u |
7 u |
Value |
$0.25 |
$0.05 |
Total value |
3.25 u |
0.35 u |
65% =
65100 =
1320Cost of each potato
= 0.25 - 0.20
= $0.05
Total cost of the vegetables
= 3.25 u + 0.35 u
= 3.6 u
3.6 u = 273.60
1 u = 273.60 ÷ 3.6 = 76
Number of yams sold
= 13 u
= 13 x 76
= $988
(b)
Amount collected from the sale of potatoes
= 0.35 u
= 0.35 x 76
= $26.60
Answer(s): (a) 988; (b) $26.60
