At a fruit stall, 364 starfruits were sold in the morning and ⁵₈ of the remaining starfruits were sold in the afternoon. As a result, the number of starfruits left became ¹₄ of the total number of starfruits at first. Given that the starfruits were sold at $4.40 in packs of seven starfruits, how much did the fruit stall receive from the sale of the starfruits in the afternoon?
Fraction of the remaining starfruits left
= 1 - ⁵₈
= ³₈

Make numerators the same.
³₈ of remaining starfruits = ¹₄ of total starfruits
³₈ of remaining starfruits = ³₁₂ of total starfruits

12 u - 8 u = 364
4 u = 364
1 u = 364 ÷ 4 = 91

Number of starfruits sold in the afternoon
= 5 u
= 5 x 91
= 455

Number of packs of seven starfruits sold in the afternoon
= 455 ÷ 7
= 65

Amount received for starfruits sold in the afternoon
= 65 x 4.40
= $286

Answer(s): $286
