In a supermarket, 75% of the number of vegetables sold were beets and the rest were potatoes. Each beet cost 25¢ and each potato cost 10¢ less than the cost of each beet. Given that $209.70 was collected from the sale of the vegetables,
- How many beets were sold?
- How much was collected from the sale of the potatoes only?
(a)

Beets |
Potatoes |
Number |
3 u |
1 u |
Value |
$0.25 |
$0.15 |
Total value |
0.75 u |
0.15 u |
75% =
75100 =
34Cost of each potato
= 0.25 - 0.10
= $0.15
Total cost of the vegetables
= 0.75 u + 0.15 u
= 0.9 u
0.9 u = 209.70
1 u = 209.70 ÷ 0.9 = 233
Number of beets sold
= 3 u
= 3 x 233
= $699
(b)
Amount collected from the sale of potatoes
= 0.15 u
= 0.15 x 233
= $34.95
Answer(s): (a) 699; (b) $34.95
