Question

Sal's Plumbing charges $25 for a service call plus $50 per hour of service. Write the equation.

:: y = 50x - 25
#: y = 50x + 25
y = -50x + 25

Answer 1

Answer: y = $50x + $25

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
