In a stall, 75% of the number of vegetables sold were turnips and the rest were ginger. Each turnip cost 50¢ and each ginger cost 20¢ less than the cost of each turnip. Given that $235.80 was collected from the sale of the vegetables,
- How many turnips were sold?
- How much was collected from the sale of the ginger only?

75% =
75100 =
34Cost of each ginger
= 0.50 - 0.20
= $0.3
Total cost of the vegetables
= 1.5 u + 0.3 u
= 1.8 u
1.8 u = 235.80
1 u = 235.80 ÷ 1.8 = 131
Number of turnips sold
= 3 u
= 3 x 131
= $393
(b)
Amount collected from the sale of ginger
= 0.3 u
= 0.3 x 131
= $39.30
Answer(s): (a) 393; (b) $39.30
