Question

A lifetime membership to the zoo cost $30 and then just $2 per visit. What is the maximum number of visits that can be made for $50 and is it modeled by a linear function or a exponential function?

Answer 1

30+2x= 50

2x= 20
x= 10 visits

Answer 2

Explanation:

The situation can be represented through a linear function

Amount remaining from
`50\\` dollars after paying an initial lifetime membership fee of
`30\\` dollars

`= 50-30\\= 20\\` dollars

The charge of one trip is $
`2\\`

Number of trips that can be done in $
`20\\`

`= (20)/(2) \\= 10\\`

So the equation for this scenario can be written as

`X = 30 + 2n\\`

X is the total money

n is the number of trips
