Answer 1

The correct answer is $25.

To find the slope, we need to determine the rate of change in cost per month. We can do this by subtracting the cost of the initial month from the cost of the final month and then dividing by the number of months.

(149 - 74) / (4 - 1) = 75 / 3 = 25

Therefore, the monthly cost is $25.
