selling price per apple

Question

Celia bought 12 apples, ate two of them, and sold the rest at $0.20 more per apple than she paid. Her total profit was $1.00. How much did she sell each apple for? Make a chart

Answer 1

c represents the cost per apple

p represents profit

s represents the selling price

 

p = s - c

1 = 10(c + 0.20) - 12c

1 = 10c + 2 - 12c

-1 = -2c

0.50 = c

 

Now you know the cost, what was the selling price?

 

Answer 2

Celia sold each apple at $1,7, she bought each apple at $1.5
