Answer 1

To find the slope, or the monthly cost of the gym membership, we need to determine the change in cost per month.

Using the values from the table:

• For 1 month: $74
• For 2 months: $99
• For 3 months: $124
• For 4 months: $149

Let's calculate the cost increase for each subsequent month:

1. From 1 to 2 months: \[ 99 - 74 = 25 \]
2. From 2 to 3 months: \[ 124 - 99 = 25 \]
3. From 3 to 4 months: \[ 149 - 124 = 25 \]

The increase in cost for each month is consistently $25.

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

The correct response is: $25.
