In a supermarket, 55% of the number of vegetables sold were sweet potatoes and the rest were radishes. Each sweet potato cost 50¢ and each radish cost 20¢ less than the cost of each sweet potato. Given that $188.60 was collected from the sale of the vegetables,
- How many sweet potatoes were sold?
- How much was collected from the sale of the radishes only?
(a)
|
Sweet Potatoes |
Radishes |
Number |
11 u |
9 u |
Value |
$0.50 |
$0.3 |
Total value |
5.5 u |
2.7 u |
55% =
55100 =
1120Cost of each radish
= 0.50 - 0.20
= $0.3
Total cost of the vegetables
= 5.5 u + 2.7 u
= 8.2 u
8.2 u = 188.60
1 u = 188.60 ÷ 8.2 = 23
Number of sweet potatoes sold
= 11 u
= 11 x 23
= $253
(b)
Amount collected from the sale of radishes
= 2.7 u
= 2.7 x 23
= $62.10
Answer(s): (a) 253; (b) $62.10
