Question

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?

Answer 1

Let x = number of yearbooks
10 = profit per yearbook
When 10x= 12000 they will have their money back.

Answer 2

Take the no. of yearbooks print as x and then use the general equation ie, 5x+120000-15x=0
