Question

Please help:) Anyone?

You attend an amusement park with your family. Your parents buy you an all-ride pass for $20, shown as f(x). Instead of getting a pass, your parents decide to pay $4 for each ride they take, shown as g(x). What function shows the correct combination of these two functions to represent the total cost to them of attending the amusement park that day, shown as h(x)?

f(x) = 20x, g(x) = 4, h(x) = 20x + 4
f(x) = 20, g(x) = 4, h(x) = 4 + 20
f(x) = 20, g(x) = 4x, h(x) = 4x + 20
f(x) = 20x, g(x) = 4x, h(x) = 20x + 4x

Answer 2

Is $20 flexible or fixed? Please show your best work.

Answer 3

? What do you mean?

Answer 4

@tkhunny I do bot understand

Answer 5

What happens after you pay $20 for an all-ride pass? Do you pay any more for that, later, or is it a fixed fee that never changes throughout the course of the day?

Answer 6

Since $20 is all-day, it'd be constant, since nothing will ever change it.
f(x) = 20
However, it says "FOR EACH" ride, it costs 4 dollars, so depending on how many rides you took, that's how many $4s you'd have to pay, so the more you ride, the more you pay.
g(x) = 4x

h(x) is just adding them together, can you figure that out?
