Answer 4

yeeah?

Answer 5

You have to calculate \(\rm revenue - profit\) to get the cost.

Answer 6

like? what? which formula how?

Answer 7

```
var x;
revenue = 200 - 2x^2;
profit = 3x^2 + 245x + 210;
cost = revenue - profit;
print(cost);

Answer 8

I don't know what programming language that is, but do you get what this question means looking at the program?

Answer 9

Correction:
```
print(cost,x);
```

Answer 10

Yeah! :) Wow the way you declare the variables are like JavaScript, and it's printed kinda like PHP lol. :) But it's so funny now that you explain it that way I understand totally! :D

Answer 11

? cost,x?

Answer 12

what's the var x?

Answer 13

undeclared? empty?

Answer 14

Okay, I don't wanna confuse you, so take it as `print(cost)`

Answer 15

undeclared.

Answer 16

Hey I get 10 when solving revenue, but I can't seem to be able to solve profit, I run into issues... (you know, this one: 3x^2 + 245x + 210) Thanks soo much for your time! :D

Answer 17

In your question, you just assume \(x\) is something and then you find \(200 - 2x^2 - (3x^2 +245x +210)\).

Answer 18

Sorry, that is \(200x - 2x^2 -(3x^2 + 245x + 210)\).

Answer 19

Thank so much for your response. :) I will try to solve it further tomorrow. Thanks. :D
