The cost formula for a company can be modeled by C=42x+6600C=42x+6600 where xx represents the number of items made. A formula for the company's income is modeled with R=72xR=72x, where xx is the number of items sold. A company will break even when it costs equal its income.

How many items must a company make and then sell to break even? Answer:

2.A junk yard pulls parts off of wrecked vehicles and sells them to a wholesaler. If its revenue function is R(x)=21xR(x)=21x and the cost function is C(x)=11x+230C(x)=11x+230. The number of parts that the junk yard must sell to break even is parts.
