12 + 3n = 27
n = 5
Total time = n+1 hrs = 6 hrs
We take n+1 as the initial rental 12$ has one hour included.
B is the correct answer.

Total Rent = Rent for First Hour + No of Hours * Rate per hour
27 = 12 + 3 ( No of Hours )
15 = 3 ( No of Hours )
Or, No of Hours ( above first hour) = 5 hours...
So, Total hours worked is 6 hours ( 5 + 1 )
Answer will be (B)

let \(n\) be the total number of renting hours for the tool.
then,
\(Total Rent = 12 +3(n-1)\)
As given, \(Total Rent=27\)
so, \(27=12+3(n-1)\)
\(3(n-1)=27-12=15\)
\(n-1=\frac{15}{3}\)
\(n-1=5\)
\(n=6\)
Answer B

We can create the equation in which h = the total number of hours of the rental. Note that she paid $12 for the first hour and $3 per hour for the remaining (h - 1) hours. Thus, we have:
12 + 3(h - 1) = 27
12 + 3h - 3 = 27
3h = 18
h = 6
Answer: B

\(\frac{27 - 12}{3}\)
Or, \(\frac{15}{3}\)
Or, 5 Hours + 1 Hour ( $ 12) , Answer must be (B) 6 Hours
_________________
n = total hours of tool rental
12 + 3(n-1) = 27
12 + 3n - 3 = 27
9 + 3n = 27
3n = 18
n = 6
Answer is B.
12 + 3(n-1) = 27
12 + 3n - 3 = 27
9 + 3n = 27
3n = 18
n = 6
Answer is B.
AbdurRakib
Let the total hour is \(x\)
So,
\(12+(x-1)3=27\)
\(12+3x-3=27\)
\(3x=27-9=18\)
\(x= \frac{18}{3}=6\)
\(x= 6\)
The answer is \(B.\)

Total Rent paid for additional hours = Total amt paid - Rent for the first hour
=> 27 - 12 = 15
15/3 = 5 hrs
Total hours = 5 + 1 = 6
=> 27 - 12 = 15
15/3 = 5 hrs
Total hours = 5 + 1 = 6

\(\frac{27-12}{3} => \frac{15}{3} = 5\), Hours rented is 5+1 = 6, answer will be (B)
_________________
12 + 3(X) = 27
Solve for ; X =5. So the total hours will be 5+1=6
Solve for ; X =5. So the total hours will be 5+1=6
