The slope, or monthly cost, can be found by finding the change in cost for each additional month.
From month 1 to month 2, the cost increased by $25 ($99 - $74).
From month 2 to month 3, the cost increased by $25 ($124 - $99).
From month 3 to month 4, the cost increased by $25 ($149 - $124).
Since the increase in cost is always $25, the monthly cost, or slope, is $25.
Therefore, the correct answer is $25.
