To find the slope, or the rate at which the cost increases per month, we can look at the change in cost divided by the change in number of months.
For example, from month 1 to month 2, the cost increases by $99 - $74 = $25.
The change in number of months is 2 - 1 = 1.
So, the slope, or monthly cost, is $25/1 = $25.
Therefore, the correct answer is $25.
