I need help figuring out what this question needs to be written like to help solve it?
If starting a new business you have a sales price for specialty pizza at $15 each but you have a fixed cost of $55 and $4 for labor how would you write this problem to figure out how to establish an equation to determine the revenue? and establish an equation to determine total cost? and how many pizza's must be sold to break even? The formula for profit and loss is profit=revenue-cost (p=r-c)
