The equation for the total amount charged is y = 60 + 45x
How to create the equation?
The given parameters are:
Rate = $60 per service
Installation = $45
Let y represents the total charges and x represents the number of services.
So, we have
y = Installation + Rate * x
This gives
y = 60 + 45 * x
y = 60 + 45x
