Step-by-step explanation:
Let \( x \) be the number of hours the car is rented. The total cost (\( C \)) is given by the sum of the rental fee and the hourly charge:
\[ C = 75 + 10x \]
The problem states that the total cost is $115. So, we can set up an equation and solve for \( x \):
\[ 115 = 75 + 10x \]
Subtracting 75 from both sides:
\[ 10x = 40 \]
Dividing both sides by 10:
\[ x = 4 \]
Therefore, it will take 4 hours for the total cost to be $115.
Answer:
4 hours
Step-by-step explanation:
C=75+10h
The problem states that the total cost is $115, so we can set up the equation:
115=75+10h
10ℎ=115−75
10h=115−75
10ℎ=40=4
h=4
