Answer:
P(x)=3x-150
Step-by-step explanation:
It is given that,
Daily revenue, R(x) = 5x, x is the number of customers that visit the gym each day
The daily cost pf the gym, C(x) = 2x+150
We need to find the profit function. It is given by :
P(x) = R(x) - C(x)
P(x) = 5x-(2x+150)
P(x) = 5x-2x-150
P(x)=3x-150
So, the correct option is (c) "P(x)=3x-150".
