Question 66683
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.
C(x)=10x+40
--------------
(b) Graph the cost equation. 
{{{graph(300,200,-1,25,-1,100,10x+40)}}}
