Please help me answer. I do not understand inequalities.

Answer:
90
5 + .50x = 50
Step-by-step explanation:
We have a flat fee of 5 dollars, so that is the constant in the equation. It costs 50 cents per ticket.
So....
5 + .50x = 50
50 - 5 = 45
.50x = 45
45/.50 = 90
You can buy 90 tickets if you have 50 dollars to spend.
