The amount of revenue in dollars, y, that Amahd receives from selling x posters is given by the equation y = 4x. The cost of producing x posters is given by the equation below.

How many posters does Amahd need to sell so that the cost and revenue are equal
A. 3
B. 20
C. 50
D. 200

B: 20

Step-by-step explanation:

You are given two functions that are both equal to y. What you would do is set each function equal to y and solve:

4x=3/2x + 50

Next you would subtract 3/2x to isolate the x to one side:

5/2x=50

Then you would multiply by 2/5 to get rid of the fraction so all you’re left with is x=__

x=20
