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=4050, n=3000, and e=300, what is the value of c?

Answer 1

c = 1.45

Explanation:

Solving the equation for c, we find ...

p +e = nc

c = (p +e)/n

Filling in the values given, we have ...

c = (4050 +300)/3000 = 4350/3000 = 1.45

The value of c is 1.45.
