Mav was comparing the price of ground beef at two stores. the equation y=4.81x represents the total cost, in dollars and cents, y, that it costs for x pounds of ground beef at supergrocery b. at supergrocery a, 4 pounds of ground beef costs $37.96.
how much more expensive is it, per pound, to buy ground beef at supergrocery a than at supergrocery b?
