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).

The revenue for a sandwich shop is directly proportional to its advertising budget. When the owner spent $2000 a month on advertising, the revenue was $120,000. If the revenue is now $180,000, how much is the owner spending on advertising?



(a)If the fixed cost is $40 and the variable cost is $10, write the cost equation

(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)?
