In a supermarket, 65% of the number of vegetables sold were sweet potatoes and the rest were beets. Each sweet potato cost 25¢ and each beet cost 20¢ less than the cost of each sweet potato. Given that $255.60 was collected from the sale of the vegetables,
- How many sweet potatoes were sold?
- How much was collected from the sale of the beets only?
(a)
|
Sweet Potatoes |
Beets |
Number |
13 u |
7 u |
Value |
$0.25 |
$0.05 |
Total value |
3.25 u |
0.35 u |
65% =
65100 =
1320Cost of each beet
= 0.25 - 0.20
= $0.05
Total cost of the vegetables
= 3.25 u + 0.35 u
= 3.6 u
3.6 u = 255.60
1 u = 255.60 ÷ 3.6 = 71
Number of sweet potatoes sold
= 13 u
= 13 x 71
= $923
(b)
Amount collected from the sale of beets
= 0.35 u
= 0.35 x 71
= $24.85
Answer(s): (a) 923; (b) $24.85
