he amount of revenue in dollars, y, that Jason receives from selling x posters is given by the equation y equals 4 x . The cost of producing x posters is given by the equation y equals space 1 half x space plus 280 . How many posters does Jason need to sell so that the cost and revenue are equal?

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.
