Question

Desmond receives 400 kg of bananas for which he pays $0.75 per kg. on average, 8% of the bananas will spoil. find the selling price per kg to obtain a 75% profit on cost.

Answer 1

What he pays: $0.75(400) = $300

He wants a profit of $225 (0.75 times 300)

After spoilage he has 368 kg (0.92 times 400)

p represents the selling price

368p = $525
