Answer:

A swimming pool charges an entrance fee of $2 per person plus $0.25 for each 10 minutes they spend in the pool.  How much did it cost for Katy to swim for 90 minutes?

let y = total cost

let x = number of 10 minute periods spent in pool

⇒ y = 0.25x + 2

If Katy spent 90 minutes in the pool, x = 9:

⇒ y = 0.25 x 9 + 2 = 4.25

So it cost Katy $4.25 to swim for 90 minutes.
