Your friend has $100 when he goes to the fair. He spends $10 to enter the fair and $20 on food. Rides at the fair cost $2.00 per ride. Which function can be used to determine how much money he has left over after x rides?
f(x) = 2x + 70
f(x) = 2x + 70
f(x) = 2x  70
f(x) = 30x + $100

Best ResponseYou've already chosen the best response.0@FEARLESS_JOCEY, That is correct. Because he has $70, and if he gets on 4 rides, 2*4=8+70 which is the same as $70$8, so that is correct.
