1 thought on “The cost of 100 eggs equals the selling price of 80 eggs. What is the percentage profit?”

1. Step-by-step explanation:

   Cost price of 1 egg = x

   Cost price of 100 eggs = 100x

   Cost price of 100 eggs = Selling Price of 80 eggs = 100x

   Cost price of 80 eggs = 80x

   We can see Selling Price of 80 eggs is greater than Cost price of 80 eggs

   Therfore, profit is incurred

   [tex]profit\% = \frac{profit}{cost \: price} \times 100[/tex]

   [tex]profit\% = \frac{(selling \: price – cost \: price)}{cost \: price} \times 100[/tex]

   [tex] = \frac{(100x – 80x)}{80x} \times 100[/tex]

   [tex] = \frac{20x}{80x} \times 100[/tex]

   [tex] = \frac{1}{4} \times100[/tex]

   [tex] = 25\%[/tex]
