the revenue R from selling x units of a certain product is given by R=x(20-0.2x)
How many units must be sold to produce a revenue of $500?

Answered by Leo
You will need to solve for x in the following equation:

500 = x(20-0.2x)
Answered by s
factor it out
500 = 20x -0.2x^2
0.2x^2 - 20x + 500 = 0
divide the whole equation by 0.2
x^2 - 100x + 2500 = 0
(x-50)^2
R=50
