Juanita is an HVAC repair person. She charges a $125 home-visit fee and $60 per hour, with the first two hours free. Which equation could Janice use to calculate the cost, c, to have Juanita work at her house for 6 hours?
A) c=125+60(6−2)
B) c=125+60(6)
C) c=125+60(6+2)
D) c=(125+60)(6−2)
The first two hours are free, so Juanita will be charging for a total of 4 hours of work. The cost of those 4 hours will be 4 times $60, or $240. She also charges a $125 home-visit fee, so the total cost will be $240 + $125, or $365. Therefore, the correct equation is:
B) c=125+60(6)
no,
the choice you made does not produce the answer you actually worked out
You are correct, I apologize for that mistake. I made an error in my calculation. The correct answer is:
C) c=125+60(6+2)
To get 6 hours of work, we need to consider the first two hours as free. That leaves a total of 4 hours of chargeable work. So the equation becomes:
c = 125 + 60(4)
Simplifying this gives:
c = 125 + 240
c = 365
Therefore, the total cost for Juanita to work at Janice’s house for 6 hours would be $365.
Wrong again, I hope you are not guessing.
besides , again your work does not correspond to the choice of answers
you made, furthermore, it is different from your first wrong answer.
I apologize for the confusion. You are correct that my previous answers were incorrect. The correct equation to calculate the cost, c, to have Juanita work at Janice's house for 6 hours is:
c = 125 + 60(6-2)
This is because the first two hours are free, and the remaining 4 hours are charged at a rate of $60 per hour. Solving this equation gives:
c = 125 + 60(4)
c = 365
Therefore, the cost to have Juanita work at Janice's house for 6 hours is $365. Again, I apologize for the previous errors.
To calculate the cost, c, to have Juanita work at Janice's house for 6 hours, we need to consider the different components of the cost.
First, there is a $125 home-visit fee that is charged regardless of the hours worked.
Next, there is an hourly rate of $60 per hour, but the first two hours are free. So for the remaining hours (after the first two), we have to multiply the cost per hour ($60) by the number of hours worked minus 2.
Therefore, the equation that can be used to calculate the cost, c, is:
c = 125 + 60(6 - 2)
So, the correct answer is:
A) c = 125 + 60(6 - 2)
