To find the slope, we need to find the change in cost divided by the change in number of months.
(change in cost) / (change in number of months) = (final cost - initial cost) / (final number of months - initial number of months)
Using the table:
(149 - 74) / (4 - 1) = 75 / 3 = 25
Therefore, the slope, or monthly cost, is $25.
