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
The top answer on your screen is the answer. Hope this help
2x + 5y = 2
-3x - y =-3
-3x - y = -3
y = 3x - 3
substitute y = 3x - 3 into the first equation.
2x + 5y = 2
2x + 5(3x - 3) = 2
2x + 15x - 15 = 2
17x - 15 = 2
solve for x in 17x - 15 = 2
17x - 15 = 2
17x = 2 + 15
17x = 17
x = 1
substitute x = 1 into y = 3x - 3
y = 3x - 3
y = 3(1) - 3
y = 3 - 3
y = 0
(1, 0) << the answer
hope this helped, God bless!
