C = 13x + 20,000
R = 15x


break even when revenue equals cost.


C = R when 13x + 20,000 = 15x.


start with 13x + 20,000 = 15x
subtract 13x from both sides of the equation to get 20,000 = 2x
solve for x to get x = 10,000


break even occurs when the number of units produced and sold is 10,000


R = 15x = 15 * 10,000 = 150,000


C = 20,000 + 13 * 10,000 = 20,000 + 130,000 = 150,000
