Final answer:
The function R(x) represents the monthly revenue received by the online shopping club when x represents the price increase. R(x) = 4800x - 200x^2 + 48,000.
Step-by-step explanation:
To write a function that represents the monthly revenue received by the online shopping club, we can start by determining the number of members remaining after each price increase.
Since the club loses approximately 200 members for each $1 increase in the membership fee, we can calculate the number of members as 4,800 - 200x, where x represents the price increase.
Next, we multiply the number of members by the monthly fee to find the monthly revenue.
Therefore, the function R(x) that represents the monthly revenue is given by:
R(x) = (4,800 - 200x)(8 + x), which simplifies to:
R(x) = 4800x - 200x^2 + 48,000.
