Answer 1

A. multiplication

Explanation:

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.

Answer 2

Hi there.

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.

To find the total revenue, we multiply.

2 · 60 = $120 in pastries

Now we just apply that to your word problem.

The answer is a. multiplication.
