An online shopping club has 4,600 members when it charges​ $9 per month for membership. For each​ $1 monthly increase in membership​ fee, the club loses approximately 200 of its existing members. Write and simplify a function R to represent the monthly revenue received by the club when x represents the price increase.

We have that

 

Revenue  =  Members  *  (Cost Per Member)

 

R  = (4600 - 200x) ( 9 + 1x)

 

Where x represents the number of $1  increases

 

 

Here's the revenue graph : https://www.desmos.com/calculator/absvn92q0v
