At a fruit stall, 231 pears were sold in the morning and ⁴₇ of the remaining pears were sold in the afternoon. As a result, the number of pears left became ¹₆ of the total number of pears at first. Given that the pears were sold at $4.50 in packs of six pears, how much did the fruit stall receive from the sale of the pears in the afternoon?
Fraction of the remaining pears left
= 1 - ⁴₇
= ³₇

Make numerators the same.
³₇ of remaining pears = ¹₆ of total pears
³₇ of remaining pears = ³₁₈ of total pears

18 u - 7 u = 231
11 u = 231
1 u = 231 ÷ 11 = 21

Number of pears sold in the afternoon
= 4 u
= 4 x 21
= 84

Number of packs of six pears sold in the afternoon
= 84 ÷ 6
= 14

Amount received for pears sold in the afternoon
= 14 x 4.50
= $63

Answer(s): $63
