Jerald is having drain issues at his home and decides to call a plumber. The plumber charges $45 to come to his house and $50 for every hour they work. If the plumber charges Jerald a total of $250, how many hours did the plumber work?
Write and solve an equation to determine the number of hours worked by the plumber.
45x + 50 = 250; x = 4.4 hours"
45x − 50 = 250; x = 6.7 hours"
50x + 45 = 250; x = 4.1 hours"
50x − 45 = 250; x = 5.9 hours"
The correct equation to determine the number of hours worked by the plumber is:
50x + 45 = 250; x = 4.1 hours
To determine the number of hours worked by the plumber, you can write the equation:
45x + 50 = 250
Where x represents the number of hours worked.
Simplifying the equation gives:
45x = 200
To solve for x, divide both sides of the equation by 45:
x = 200 / 45
This gives:
x ≈ 4.4 hours
Therefore, the correct answer is:
The plumber worked approximately 4.4 hours.
To solve this problem, we can set up an equation using the given information.
Let's say the number of hours the plumber worked is represented by 'x'.
According to the information provided, the plumber charges $45 to come to the house and $50 for every hour they work. So, the total cost can be calculated as:
Total Cost = Cost for plumber to come + (Cost per hour * Number of hours worked)
This can be written as an equation:
45 + 50x = 250
Now, let's solve the equation:
45 + 50x = 250
Subtracting 45 from both sides:
50x = 250 - 45
50x = 205
Dividing both sides by 50:
x = 205/50
x = 4.1
Therefore, the plumber worked for 4.1 hours.
So, the correct answer is:
50x + 45 = 250; x = 4.1 hours
