The equation in slope-intercept form that models the situation is:
C = 60t + 10
In this equation, C represents the total cost and t represents the number of months spent with the tennis club.
The startup fee of $60 is a one-time cost, so it is represented by the constant term in the equation (10). The monthly fee of $10 is multiplied by the number of months (t) to account for the ongoing cost.
To understand how this equation works, let's consider an example:
If Jamal has been with the tennis club for 3 months, we can substitute t = 3 into the equation:
C = 60(3) + 10
C = 180 + 10
C = 190
This means that after 3 months, the total cost (C) for Jamal would be $190.
Similarly, if we want to find the total cost after 6 months, we can substitute t = 6 into the equation:
C = 60(6) + 10
C = 360 + 10
C = 370
Therefore, after 6 months, the total cost (C) for Jamal would be $370.
In summary, the equation C = 60t + 10 models the situation where C represents the total cost and t represents the number of months spent with the tennis club. The equation allows us to calculate the total cost based on the number of months spent in the club.
