The slope represents the rate of change of the cost per month. We can use the formula for slope:
slope = (change in y)/(change in x)
In this case, y is the cost and x is the number of months. Let's choose two points from the table to calculate the slope. We can choose (1, 74) and (2, 99):
slope = (99-74)/(2-1) = 25
Therefore, the slope or monthly cost for the gym membership is $25. Answer: C. $25.
