The cost of producing a number of items x is given by C=mx+b, inwhich b is the fixed cost and m is the variable cost (the cost of producing one more item).

Question

(a) If the fixed cost is $40 and the variable cost is $10, write the cost equation.
Could someone help me please with this problem ASAP!!

How do I graph this/ Could you explain how I do this as well?

This is algebra. You have all the parts for the cost function. C=10.*X + 40.

This is a simple line. Starts at 40 on the y-axis and rises 10 for every x.
