At a fruit stall, 336 kiwis were sold in the morning and ⁵₈ 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 $4.20 in packs of eight kiwis, how much did the fruit stall receive from the sale of the kiwis in the afternoon?
Fraction of the remaining kiwis left
= 1 - ⁵₈
= ³₈

Make numerators the same.
³₈ of remaining kiwis = ¹₅ of total kiwis
³₈ of remaining kiwis = ³₁₅ of total kiwis

15 u - 8 u = 336
7 u = 336
1 u = 336 ÷ 7 = 48

Number of kiwis sold in the afternoon
= 5 u
= 5 x 48
= 240

Number of packs of eight kiwis sold in the afternoon
= 240 ÷ 8
= 30

Amount received for kiwis sold in the afternoon
= 30 x 4.20
= $126

Answer(s): $126
