Question

The table below shows the cost for a gym membership at the local fitness center with an initial start-up fee charged in the first month Find the slope or monthly cost.

(Number of months:1,2,3,4
(cost)$74,99,124,149

Use the table to answer the question

Answer 1

To find the slope, we can use the formula for finding the slope between two points:

slope = (change in y)/(change in x)

In this case, the change in y is the change in cost and the change in x is the change in number of months.

For the given table:

(Number of months:1,2,3,4
(cost)$74,99,124,149

The change in y between the first and second months is 99 - 74 = 25.
The change in x between the first and second months is 2 - 1 = 1.

Therefore, the slope between the first and second months is 25/1 = 25.
