The profit earned by a hot dog stand is a linear function of the number of hot dogs sold. It costs the owner $48 dollars each
morning for the day's supply of hot dogs, buns and mustard, but he earns $2 profit for each hot dog sold. Which equation
represents y, the profit earned by the hot dog stand for x hot dogs sold?
y=48x-2
y=48x+2
y=2x-48
y=2x+48
