Question

Can Someone Help ^.^ <3

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 $4.00 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

@johnweldon1993 /.\ can i have a bit of help

Answer 2

Alright so g(x) would be you...ad that is just 20 dollars for an all day thing..(a constant) so g(x) = 20

h(x) however...is a variable because we don't know how many rides they are going to ride...but we do know each ride is 4 dollars....so 4x ...we ALSO know they paid for your ticket...which was 20...so

g(x) = 20
and
h(x) = ?

Answer 3

im lost o.o

Answer 4

-Let x be the number of rides you take. The price you pay will always be $20 no matter how many rides you take, so f(x)=20 for every 'x'
-Let x be the number of rides your parents take. Each ride costs $4 so the price will depend on how many rides they take ie. The price will be $4 times the nbr of rides (x) g(x)=4x
-The total cost will be the addition of the 2 functions.

Answer 5

d?

Answer 6

Not quite @jadee27p remember f(x) doen't change with x, it's constant.
