LightYagami · Answer

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.

Abhishek009 · 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)

SeregaP · Answer

great question!
12+3*hours=27
We need  
h=(27-12)/3
h=5

1+5=6

Answer is B 
Beware of not writing 5!

HasnainAfxal · Answer

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

ScottTargetTestPrep · Answer

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

sunngupt11 · Answer

12(1) + 3(n) = 27
n = 5
total hours = n + 1 = 6
answer B.

Abhishek009 · Answer

\frac{27 - 12}{3}

Or,  \frac{15}{3}

Or, 5 Hours + 1 Hour (  $  12) , Answer must be (B) 6 Hours

Basshead · Answer

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.

MHIKER · Answer

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.

lunalight · Answer

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

Abhishek009 · Answer

\frac{27-12}{3} => \frac{15}{3} = 5 , Hours rented is 5+1 = 6, answer will be (B)

Arvind123 · Answer

12 + 3(X) = 27

Solve for ; X =5. So the total hours will be 5+1=6
