Step-by-step explanation:

Let n = number of years since 1995

Let C = cost of gym membership in any particular year

Initial cost in 1995 = $25

Additional cost each year = $6

We can say the following:

Cost at any given year = cost in 1995 + ($6 x number of years after 1995)

Or expressed as the following :  C = 25 + 6n   (Ans)

In 2009, the number of years since 1995,

= 2009 - 1995

= 14 years

Hence, cost in 2009,

= $25 + ($6 x 14 years)

= $109 (Ans)
