Respuesta :
- Rate of change=38$
- Registration fee=40$
Equation in slope intercept form
- y=mx+b
- y=38x+40
x is no of months
now
- 458=38x+40
- 458-40=38x
- 418=38x
- x=11
11 months have passed
Answer:
11 months
Step-by-step explanation:
Given:
- Registration fee = $40
- Fee per month = $38
- Total paid to gym = $458
Let x = number of months
β Registration fee + (fee per month Γ number of months) = total paid
β 40 + 38x = 458
Subtract 40 from both sides:
β 38x = 418
Divide both sides by 38:
β x = 11
Therefore, 11 months have passed since you joined the gym.
