Question

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 1

Third option :
`h(x)=4x+20`

Explanation:

All ride pass is a one time payment that parents have to do. It will not change with the amount of rides.

So,
`f(x)=20`

Each rise will cost $4, so if you take
`x` number of rides the total amount paid will be:

`g(x)=4x`

Now we can add these two functions to find the Total amount paid for the amusement park:

`h(x)=4x+20`
