$700 (purchase) + $100 (annual cost) x 15 (years you owned the fridge) = $700 + $1500 = $2200

Function: (purchase) + (annual cost)x(number of years you owned the fridge)

Function here: $700 + $100 x, where x equals the number of years you owned the fridge

For the first part, determine the cost if you own it for 15 years. All you have to do is take the cost of the actual fridge which is $700. After that all you do is if it costs 100 dollars for one year, then for fifteen years it will cost $1500. $700 + $1500 = $1200.

A function would just be $700 + $100x where x equals number of years you own the fridge.
