A plumber charges $50 for every house call and an additional $70 for each hour of work. For one house call yesterday, the plumber earned $435.
Which equation can be solved to find the number of hours the plumber worked on the house call?
A 435 = 70x50
B 435=(50 +70)x
C 435= (x +70)+50
D 435=50x +70
x
Answer: D 435=50x +70x
thx i dont know if its right yet but thx
The correct equation that can be solved to find the number of hours the plumber worked on the house call is:
D) 435 = 50x + 70
In this equation, 'x' represents the number of hours the plumber worked, and 50x represents the additional charge for each hour of work. The equation adds the $70 charge for each house call to the total earnings of $435.
To solve this problem, we need to set up an equation that represents the given information. Let's break it down step by step:
We know that the plumber charges $50 for every house call, so the cost of the house call itself is $50.
We also know that the plumber charges an additional $70 for each hour of work. Let's assume the number of hours the plumber worked on the house call is 'x'. So, the cost of the plumber's work is 70x.
Adding the cost of the house call and the cost of the work, we have the total amount earned by the plumber, which is $435.
Now let's set up the equation based on this information:
House Call Cost + Work Cost = Total Amount Earned
$50 + $70x = $435
So, the correct equation that can be solved to find the number of hours the plumber worked on the house call is:
D) 435 = 50x + 70
