At a fruit stall, 392 pears were sold in the morning and ⁵₇ of the remaining pears were sold in the afternoon. As a result, the number of pears left became ¹₇ of the total number of pears at first. Given that the pears were sold at $4.80 in packs of eight pears, how much did the fruit stall receive from the sale of the pears in the afternoon?
Fraction of the remaining pears left
= 1 - ⁵₇
= ²₇

Make numerators the same.
²₇ of remaining pears = ¹₇ of total pears
²₇ of remaining pears = ²₁₄ of total pears

14 u - 7 u = 392
7 u = 392
1 u = 392 ÷ 7 = 56

Number of pears sold in the afternoon
= 5 u
= 5 x 56
= 280

Number of packs of eight pears sold in the afternoon
= 280 ÷ 8
= 35

Amount received for pears sold in the afternoon
= 35 x 4.80
= $168

Answer(s): $168
