Question

Each theme park charges an entrance fee plus an additional fee per ride. Write a function for each park. (3 points)

a) write a function rule for Big Wave Waterpark

b) write a function rule for Coaster City

c) write a function rule for Virtual Reality Lan

Answer 1

a)

`m = (15 - 10)/(4 - 2) = (5)/(2)`

`10 = (5)/(2) (2) + b`

`10 = 5 + b`

`b = 5`

`y = (5)/(2)x + 5`

b) The function is already given.

c)

`m = (100 - 40)/(30 - 10) = (60)/(20) = 3`

`100 = 3 (30) + b`

`100 = 90 + b`

`b = 10`

`y = 3x + 10`
