Health Club Plans 501B90
1. **State the problem:**
We have three health clubs with different payment plans. We need to match each club to its payment table and write equations representing their costs.
2. **Identify each club's table:**
- Club C has no initial fee and charges $60 per month. The table with costs starting at $0 and increasing by $60 each month matches Club C.
- Club A has a $150 initial fee and charges $45 per month. The table starting at $195 for month 1 (which is $150 + $45) matches Club A.
- Club B has a $250 initial fee and charges $35 per month. The table starting at $285 for month 1 (which is $250 + $35) matches Club B.
3. **Write equations for each club:**
The general form for cost is:
$$y = mx + b$$
where $m$ is the monthly charge (slope) and $b$ is the initial fee (y-intercept).
- Club C:
$$y = 60x + 0$$
Slope means: The cost increases by $60 every month.
Y-intercept means: There is no initial fee.
- Club A:
$$y = 45x + 150$$
Slope means: The cost increases by $45 every month.
Y-intercept means: The initial fee is $150.
- Club B:
$$y = 35x + 250$$
Slope means: The cost increases by $35 every month.
Y-intercept means: The initial fee is $250.
**Final answers:**
- Club C matches the table with costs 0, 60, 120, 180, 240, 300.
- Club A matches the table with costs 195, 240, 285, 330, 375.
- Club B matches the table with costs 285, 320, 355, 390, 425.
Equations:
- Club C: $y = 60x + 0$
- Club A: $y = 45x + 150$
- Club B: $y = 35x + 250$
