To find the slope, or monthly cost, we can look at the changes in cost over the number of months. The cost information given in the table is as follows:

  • Month 1: $74
  • Month 2: $99
  • Month 3: $124
  • Month 4: $149

To find the slope, we can calculate the cost increase between each month:

  • From month 1 to month 2: $99 - $74 = $25
  • From month 2 to month 3: $124 - $99 = $25
  • From month 3 to month 4: $149 - $124 = $25

The cost increases consistently by $25 each month.

Therefore, the slope, or monthly cost, is $25.

The correct response is:

$25
