Answer:
He should sell 0.988$ per fruit.
Step-by-step explanation:
I. When 15% is rotten so find the remain of good fruits.
15/100 = x/60
15 * 60 = 100x
900/100 = x
x = 9
Good fruit = total - rotten
= 60 - 9
So good fruit is 51
II. Find profit of 80% on cost, when cost is 28$
80/100 = x/28
2,240 = x100
x = 22.4
Profit cost = 28 + 22.4
So profit cost is 50.4$
III. Find selling price per fruit, when good fruit is 51 and profit cost is 50.4
50.4/51 = 0.988
So selling price per fruit is 0.988$
