Amembership to the gym costs $ 25 per person in 1995 .the membership cost has increased by an average of $ 6 per person for each year since 1995 .write a linear equation for the cost of a gym membership for one person since 1995. so , what is the cost of a gym membership in 2009

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)

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
