In a kiosk, 70% of the number of vegetables sold were sweet potatoes and the rest were beets. Each sweet potato cost 25¢ and each beet cost 10¢ less than the cost of each sweet potato. Given that $233.20 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 |
7 u |
3 u |
Value |
$0.25 |
$0.15 |
Total value |
1.75 u |
0.45 u |
70% =
70100 =
710Cost of each beet
= 0.25 - 0.10
= $0.15
Total cost of the vegetables
= 1.75 u + 0.45 u
= 2.2 u
2.2 u = 233.20
1 u = 233.20 ÷ 2.2 = 106
Number of sweet potatoes sold
= 7 u
= 7 x 106
= $742
(b)
Amount collected from the sale of beets
= 0.45 u
= 0.45 x 106
= $47.70
Answer(s): (a) 742; (b) $47.70
