Question

The formula p=nc-e gives the profit p when a number of items n are each sold at a cost c and expenses e are subtracted. If p = 3750, n = 3000, and e = 900, what is the value of c?

Answer 1

1.55

Explanation:

p =nc-e

p=3750, n=3000, e=900, c=?

3750 = 3000c - 900

3750 + 900 = 3000c

4650 = 3000c

3000c = 4650

c = 4650/3000

c = 1.55
