In a shop, 55% of the number of vegetables sold were turnips and the rest were sweet potatoes. Each turnip cost 25¢ and each sweet potato cost 20¢ less than the cost of each turnip. Given that $217.60 was collected from the sale of the vegetables,
- How many turnips were sold?
- How much was collected from the sale of the sweet potatoes only?

55% =
55100 =
1120Cost of each sweet potato
= 0.25 - 0.20
= $0.05
Total cost of the vegetables
= 2.75 u + 0.45 u
= 3.2 u
3.2 u = 217.60
1 u = 217.60 ÷ 3.2 = 68
Number of turnips sold
= 11 u
= 11 x 68
= $748
(b)
Amount collected from the sale of sweet potatoes
= 0.45 u
= 0.45 x 68
= $30.60
Answer(s): (a) 748; (b) $30.60
