Use the table to answer the question. Number of Months Cost ($) 1 74 2 99 3 124 4 149 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. (1 point)
The slope, or monthly cost, can be found by determining the change in cost divided by the change in the number of months.
To find the change in cost, subtract the cost in the first month from the cost in the fourth month:
Change in cost = $149 - $74 = $75
To find the change in the number of months, subtract the number of months in the first month from the number of months in the fourth month:
Change in number of months = 4 - 1 = 3
Finally, divide the change in cost by the change in number of months to find the slope, or monthly cost:
Slope = Change in cost / Change in number of months = $75 / 3 = $25
Therefore, the slope, or monthly cost, is $25.
