Problem states:

Business and finance. The cost of producing a number of items x is given by C = mx + b, in which b is the fixed cost and m is the variable cost (the cost of producing one more item).
(a)If the fixed cost is \$40 and the variable cost is \$10, write the cost equation.

My equation answer for par A is:
C = 10x + 40
