The Naturally Made Bath and Body store pays $550 a month for rent and utilities. The average cost for its products to be manufactured is about $3.00 an item. If the average price for a product sold in the store is $5.50, what will the break-even point be? Let x represent the number of products sold.

The cost function that represents the situation is
C(x)=3.00x
C(x)= 550+3.00x
C(x)=3.00=550
C(x)=550-3.00
The revenue function that represents the situation is
R(x)=3.00
R(x)=5.50x
R(x)=5.50-x
R(x)=5.50x
