$74

Answer 1

To find the slope (the monthly cost) from the given table, we can use the cost information for consecutive months.

The changes in cost over the months are:

• 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 difference in cost for each month is consistently $25.

Thus, the monthly cost (slope) is $25.
