Jim spent $13 to park for 5 hours. The parking garage charges a base rate of $4 for the first two 2 hours, and then an hourly rate for each additional hour, h. The equation 3h + 4 = 13 models Jim's parking cost. How much does each additional hour of parking cost?

A $2.50$2.50
B $3$3
C $4.50$4.50
D $5
To find the cost of each additional hour of parking, we can solve the equation $3h + 4 = 13$ for $h$. Subtracting 4 from both sides gives $3h = 9$, and dividing both sides by 3 gives $h = 3$. Therefore, each additional hour of parking costs $3. \boxed{\text{(B)}\ \$3}$
To find the cost of each additional hour of parking, we need to solve the equation 3h + 4 = 13 for h.
First, subtract 4 from both sides of the equation:
3h + 4 - 4 = 13 - 4
3h = 9
Next, divide both sides of the equation by 3:
3h/3 = 9/3
h = 3
Therefore, each additional hour of parking costs $3.
The answer is B) $3.
To find out the cost of each additional hour of parking, we need to solve the equation 3h + 4 = 13.
First, we subtract 4 from both sides of the equation to isolate the term with h:
3h = 9
Next, we divide both sides of the equation by 3 to solve for h:
h = 3
Therefore, each additional hour of parking costs $3.
So, the correct answer is B: $3.
