Answer: y = $50x + $25
Step-by-step explanation:
First, let x be equal to the hours of service and y be the total cost. Since the cost is 50 dollars per hour of service, we will write this as "y = 50x" for our equation.
Next, there is a 25-dollar charge for each call. We will add this to our equation as "y = 50x + 25."
Our equation is;
y = $50x + $25
