The question is a little confusing, but I think the answer goes like this:
135 = admission + 5x, and if she bought 10 tickets:
135 = admission + 50, so admission must have cost her $85
The function would be f(x) = 85 + 5x, where x is equal to the number of raffle tickets purchased
<span>Direct proof. A direct proof is a way of establishing the truth or falsehood of a given mathematical statement by a combination of established facts, usually axioms, lemmas and theorems. It assumes the hypothesis of a conjecture is true and then uses a series of logical deductions to prove that the conclusion as well.</span>

Distribute the .25 to get .25x + 1 - 3 = 28
Then simplify to get .25x - 2 = 28
Move the two to the right to get .25x = 30
Then divide to leave x: 30 / .25 = 120
X = 120
