Mike and kim invest $12,000 in equipment to print yearbooks for schools. each yearbook costs $5 to print and sells for $15. how many yearbooks must they sell before their business breaks even? . a. 800 yearbooks. b. 1,200 yearbooks. c. 2400 yearbooks. d. 1,800 yearbooks

To determine the break even number of yearbooks, equate the revenue with the total cost. Let x be the number of yearbooks sold so that the break even equation becomes,
                                        15x = 12000 + 5x
The value of x is 1200. Therefore, the answer is letter B. 

Letter c hope it
