Question

Tell me if I'm correct?
-Polynomials-

Answer 1

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?

Addition

Subtraction

Multiplication <---- My second guess

It cannot be determined < --- My guess

Answer 2

I think it's cannot be determined because it's two different types of equations so it might need more then one operation.

Answer 3

Well, do you know how revenue is compute?

Revenue = ??

Answer 4

@DebbieG
I believe it could be Subtraction as you have to subtract the taxes and stock prices to decide your profit.

Answer 5

Profit is not mentioned in the problem. Only revenue.

Answer 6

Revenue = ??

Answer 7

@DebbieG Revenue is the money you make before taking out taxes and paying for expenses which was what I pretty much wrote with the exception of profit x_X

Answer 8

I think you are overthinking it.

Revenue = price x quantity sold

Answer 9

you just need to find out how much money they get from the customers.........thats the revenue

Answer 10

you have a function for price in terms of x, and a function for quantity sold in terms of x.

Answer 11

@atlas So then the answer would be multiplication if I use what Debbie told me to find Revenue?

Answer 12

Right!!

Answer 13

The only question in my mind (and I think the problem is slightly vague on this) is, is the x in the price function THE SAME as the x in the quantity function? E.g., they TELL you that x in p(x) is "the number of years since the company started producing games". are we safe to assume that the x in s(x) means the same thing?

I *THINK* it's safe to assume that. But it's odd to me that they told you what x is immediately after the function p(x), and NOT after the function s(x). That would be the only reason that I can see why that "can not determine" might be thrown in there. But my first thought is "multiplication".

Answer 14

@atlas Thanks! :P

@DebbieG Oh okay, it kind of threw me off.

Answer 15

Yeah, maybe I'm overthinking it too. lol :) I would say multiplication, but might mention to the teacher that it isn't clear that the x is the same in both functions... :)

Answer 16

@DebbieG Will do. I'm also going to be taking more notes

Answer 17

@DebbieG u are right...............>Smores is also creative here to think out of the box..............a less creative person like me would have simply ticked multiplication without much ado

Answer 18

@atlas Pfffff.
