Given the following question:
Courtney has 50 dollars
She spent 10, and 15 dollars on admission and snacks
10 + 15 = 25
Each game costs 1.25, we aren't told how many games Courtney played so 1.25x (since it's x amount of games)
We are only given 50 dollars so the costs of admission, snacks, and games cannot be greater than 50.
Which means....
Your answer is option A
1.25x + 25
Representing the amount she spent
less than or equal to representing her not going over the amount of money she brought which is 50.
1.25x + 25 < or = 50
Your answer is option A.
