what do you mean by "do" the function? They gave it to you.
Surely you know that profit = revenue-cost, and they gave you both of those, so
P(x) = R(x)-C(x)
= 0.0125x^2+412x - (12225+0.00135x^2)
= 0.01115x^2 + 412x - 12225
So when does P(x)=60000? when x=174.48
so, they need 175 customers to make at least 60,000 profit.
See? Not so complicated, once you get past all the words.
Using data from past years, the economists for smith brothers inc determined that the revenue f the company can be modeled by the function R(x)=0.0125x^2+412x. In addition, the function C(x)=12225+0.00135x^2 models the total cost of doing business, where x us v the number of customers patronizing the business in both functions.
A) how many customers just there be for ssmithmith bros inc to realize am annual profit of $60000?
I have no idea how to do modeling Function
