where p is the price per hamburger, q is the demand in weekly sales, and m and b constants are certain constants you must determine. Your market studies reveal the following sales figures: when the price is set at $4 per hamburger, the sales amount to 5,920 per week, but when the price is set at $8 per hamburger, the sales drop to zero.
