The table shows the cost for a gym membership at
the local fitness center with and 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
To find the slope or monthly cost, we need to analyze the increase in cost for each additional month.
First, let's calculate the increase in cost from the first month to the second month:
Cost for the second month - Cost for the first month
99 - 74 = 25
Next, let's calculate the increase in cost from the second month to the third month:
Cost for the third month - Cost for the second month
124 - 99 = 25
Finally, let's calculate the increase in cost from the third month to the fourth month:
Cost for the fourth month - Cost for the third month
149 - 124 = 25
Since the increase in cost is the same for each additional month, the slope or monthly cost is $25.
