 Question 73562: I think I may have submitted this one before but I am really having trouble with it still. 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. This is what I came up for this part. C = 10x + 40 b) Graph the cost equation. (c) The revenue generated from the sale of x items is given by R = 50x. Graph the revenue equation on the same set of axes as the cost equation. (d) How many items must be produced for the revenue to equal the cost (the break-even point)? Answer by stanbon(60771)   (Show Source): You can put this solution on YOUR website!Business and finance.

Done (d) How many items must be produced for the revenue to equal the cost (the break-even point)? R=C 50x = 10x+40 40x=40 x= 1 (number of items that must be produced to break even) ============= Cheers, Stan H.
