Camille is attending a fundraiser. She pays for her admission and buys raffle tickets for $ 5 $5 each. If she buys 1 0 10 raffle
tatyana61 [14]
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

How do i do this problem 0.25(x+4)-3=28
KiRa [710]
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
