Jim spent $13 to park for 5 hours. The parking garage charges a base rate of $4 for the first two hours and then an hourly rate for each additional hour, how. The equation 3h+4=13 models Jim's parking cost. How much does each additional hour of parking cost?

Answer 1

To find out the cost of each additional hour of parking, we start with the equation provided:

\[ 3h + 4 = 13 \]

Here, \( h \) represents the cost of each additional hour beyond the first two hours.

1. First, we need to isolate \( 3h \): \[ 3h = 13 - 4 \] \[ 3h = 9 \]

2. Now, divide both sides by 3 to find \( h \): \[ h = \frac{9}{3} = 3 \]

Thus, each additional hour of parking costs $3.
