put this solution on YOUR website!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 equaton
In the formula

, m=variable cost and b=fixed cost
m=10 and b=40
Therefore:

Happy Calculating!!!
