The equation that represents the linear relationship of the rental company is y = 12 + 3x
How to determine the equation?
The given parameters are:
- Unit rate = $3 per hour
- Base charge = 12
Let y represent the total charges and x represent the number of hours
The equation is calculated using:
Total = Base charge + Rate * Number of hours
So, we have:
y = 12 + 3 * x
Evaluate
y = 12 + 3x
Hence, the equation for the linear relationship is y = 12 + 3x
