At a fruit stall, 288 passion fruits were sold in the morning and ⁵₇ of the remaining passion fruits were sold in the afternoon. As a result, the number of passion fruits left became ¹₅ of the total number of passion fruits at first. Given that the passion fruits were sold at $2.40 in packs of six passion fruits, how much did the fruit stall receive from the sale of the passion fruits in the afternoon?
Fraction of the remaining passion fruits left
= 1 - ⁵₇
= ²₇

Make numerators the same.
²₇ of remaining passion fruits = ¹₅ of total passion fruits
²₇ of remaining passion fruits = ²₁₀ of total passion fruits

10 u - 7 u = 288
3 u = 288
1 u = 288 ÷ 3 = 96

Number of passion fruits sold in the afternoon
= 5 u
= 5 x 96
= 480

Number of packs of six passion fruits sold in the afternoon
= 480 ÷ 6
= 80

Amount received for passion fruits sold in the afternoon
= 80 x 2.40
= $192

Answer(s): $192
