A company makes video games. The price of a video game is modeled by the function p(x) = 30x + 2, where x is the number of years since the company started producing games. The number of video games they sell is modeled by the function s(x) = 500x + 250. To find the total revenue from their video games, the company should use what operation on the polynomials?
a. multiplication
b. addition
c. it cannot be determined
d. subtraction
I think one of the best ways to understand problems like this is to use easier numbers. I'll show you what I mean.
Let's say a bakery wants to find the total revenue from pastries in a day. The price of the pastries they sell are $2 each. Let's say they sold 60 pastries in one day.
It is A because in order to find the revenue of their video games, the company would have to multiply p(x) and s(x) together at some point. I also got it correct on my quiz.
