At a fruit stall, 396 kiwis were sold in the morning and ⁵₇ of the remaining kiwis were sold in the afternoon. As a result, the number of kiwis left became ¹₅ of the total number of kiwis at first. Given that the kiwis were sold at $2.10 in packs of six kiwis, how much did the fruit stall receive from the sale of the kiwis in the afternoon?
Fraction of the remaining kiwis left
= 1 - ⁵₇
= ²₇

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

10 u - 7 u = 396
3 u = 396
1 u = 396 ÷ 3 = 132

Number of kiwis sold in the afternoon
= 5 u
= 5 x 132
= 660

Number of packs of six kiwis sold in the afternoon
= 660 ÷ 6
= 110

Amount received for kiwis sold in the afternoon
= 110 x 2.10
= $231

Answer(s): $231
