Question

In a video game, you score p game points and b triple bonus points. an expression for your score is p+3b. what is your score when you earn 245 game points and 20 triple bonus points?

Answer 1

245+3(20)
245+60
So the final score would be 305

Answer 2

When you earn 245 game points and 20 triple bonus points your score is 305 points.

Explanation:

First we analize the expression for the score.

The expression is
`p+3b`

The score is a function that depends of the variables ''p'' and ''b''. Let's write the function ''score'' as S ⇒

`S(p,b)=p+3b`

The total game points and triple bonus points must be greater than or equal to 0 ⇒
`p\geq 0\\b\geq 0`

That's the domain for the function.

To find the score, we replace
`p=245` and
`b=20` in the score expression :

`S(245,20)=245+3.(20)`

`S(245,20)=305`

Therefore, your score is 305 points.
