Savannah is deciding between two parking garages. Garage A chargers an initial fee of $9 to park plus $1.50 per hour

4 hours

Step-by-step explanation:

Assume x is the number of hours taken.

Garage A would therefore charge a total of:

= $9 + $1.50 * x

= 9 + 1.50x

Garage B would charge:

= $5 + $2.50 * x

= 5 + 2.50x

To find the number of hours it would take for them to be the same, equate both equations:

9 + 1.50x = 5 + 2.50x

9 - 5 = 2.50x - 1.50x

4 = 1x

x = 4 hours

That cost would be:

= 9 + 1.50 * 4

= 9 + 6

= $15
