James is selling fresh rolls for his new bakery. He has a fixed cost of $1500 for a cooler that can store the dough for the rolls. Each roll costs $0.50 to make, and James will sell them for $2.50 each.
Write an equation that models the relationship between profit and the number of rolls sold. Solve the equation for the number of rolls sold, and determine the break-even point. Are there any costs that the model does not account for?
