At a fruit stall, 360 apples were sold in the morning and ³₅ of the remaining apples were sold in the afternoon. As a result, the number of apples left became ¹₇ of the total number of apples at first. Given that the apples were sold at $3.20 in packs of eight apples, how much did the fruit stall receive from the sale of the apples in the afternoon?
Fraction of the remaining apples left
= 1 - ³₅
= ²₅

Make numerators the same.
²₅ of remaining apples = ¹₇ of total apples
²₅ of remaining apples = ²₁₄ of total apples

14 u - 5 u = 360
9 u = 360
1 u = 360 ÷ 9 = 40

Number of apples sold in the afternoon
= 3 u
= 3 x 40
= 120

Number of packs of eight apples sold in the afternoon
= 120 ÷ 8
= 15

Amount received for apples sold in the afternoon
= 15 x 3.20
= $48

Answer(s): $48
