At a fruit stall, 210 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 $4.60 in packs of seven 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 = 210
3 u = 210
1 u = 210 ÷ 3 = 70

Number of kiwis sold in the afternoon
= 5 u
= 5 x 70
= 350

Number of packs of seven kiwis sold in the afternoon
= 350 ÷ 7
= 50

Amount received for kiwis sold in the afternoon
= 50 x 4.60
= $230

Answer(s): $230
