In a supermarket, 75% of the number of vegetables sold were ginger and the rest were beets. Each ginger cost 25¢ and each beet cost 10¢ less than the cost of each ginger. Given that $202.50 was collected from the sale of the vegetables,
- How many ginger were sold?
- How much was collected from the sale of the beets only?
(a)
|
Ginger |
Beets |

3 u |
1 u |
Value |
$0.25 |
$0.15 |
Total value |
0.75 u |
0.15 u |
75% =
75100 =
34Cost of each beet
= 0.25 - 0.10
= $0.15
Total cost of the vegetables
= 0.75 u + 0.15 u
= 0.9 u
0.9 u = 202.50
1 u = 202.50 ÷ 0.9 = 225
Number of ginger sold
= 3 u
= 3 x 225
= $675
(b)
Amount collected from the sale of beets
= 0.15 u
= 0.15 x 225
= $33.75
Answer(s): (a) 675; (b) $33.75
