Question

Problem

Phil received a prize of x dollars from a poker tournament. The tournament cost him 100 dollars to enter.
What were Phil's net winnings from the tournament?
Write your answer as an expression.

Answer 1

you could write is this way (y+x)-100

Answer 2

Phil gets x dollars, but before he gets x dollars, he needs to pay 100 dollars to enter the tournament. Therefore the net winning is not x dollars but you should substract 100 dollars from x.

So, the expression of the net winning will be

`\boxed{x-100}`
