A plumber charges a $45 fee to make a house call and then $25 for each hour of labor. The plumber uses an equation in the form es027-1.jpg to determine the amount to charge each customer. What is the value of m in the equation?

Respuesta :

m=slope
In this case the slope would be $25
y=mx+b
y=25x+45

Answer: m=25

Answer:

Value of m is 25.

Step-by-step explanation:

Given:

Permanent charge of Plumber = $ 45

Amount per hour of labor = $ 25

Plumber uses the Equation,

Total Amount, y = mx + c

To find: Value of m in the equation.

Let x be the number of hour of labor of the Plumber.

Then cost of labor = 25 × x = 25x

⇒ Total Amount of Plumber = 25x + 45

So, y = 25x + 45

So comparing with given equation,

m = 25

Therefore, Value of m is 25.
