In a stall, 75% of the number of vegetables sold were garlics and the rest were sweet potatoes. Each garlic cost 25¢ and each sweet potato cost 10¢ less than the cost of each garlic. Given that $194.40 was collected from the sale of the vegetables,

75100 =
34Cost of each sweet potato
= 0.25 - 0.10
= $0.15
Total cost of the vegetables
= 0.75 u + 0.15 u
= 0.9 u
0.9 u = 194.40
1 u = 194.40 ÷ 0.9 = 216
Number of garlics sold
= 3 u
= 3 x 216
= $648
(b)
Amount collected from the sale of sweet potatoes
= 0.15 u
= 0.15 x 216
= $32.40
Answer(s): (a) 648; (b) $32.40
