In a stall, 70% of the number of vegetables sold were turnips and the rest were sweet potatoes. Each turnip cost 50¢ and each sweet potato cost 20¢ less than the cost of each turnip. Given that $189.20 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?

70% =
70100 =
710Cost of each sweet potato
= 0.50 - 0.20
= $0.3
Total cost of the vegetables
= 3.5 u + 0.9 u
= 4.4 u
4.4 u = 189.20
1 u = 189.20 ÷ 4.4 = 43
Number of turnips sold
= 7 u
= 7 x 43
= $301
(b)
Amount collected from the sale of sweet potatoes
= 0.9 u
= 0.9 x 43
= $38.70
Answer(s): (a) 301; (b) $38.70
