Question 1208082
.
The short-term (no more than 24 hours) parking fee F(in dollars) for parking x hours at 
O’Hare International Airport’s main parking garage can be modeled by the piecewise function F(x).

Top portion of F(x): 3 if 0 < x <= 3

Middle portion of F(x): 5•int(x + 1) + 1 if 3 < x < 9

Bottom portion of F(x): 50 if 9 <= x <= 24

Determine the fee for parking in the short-term parking garage for 8 hours and 24 minutes.
~~~~~~~~~~~~~~~~~~~~


<pre>
8 hours and 24 minutes is  8{{{24/60}}} hours,  or  8{{{2/5}}}  hours,  or  8.4 hours.


So, in this problem  x = 8.4.


This value is between 3 and 9,  so we apply the middle portion of F(x).


First, we calculate x+1 = 8.4+1 = 9.4.

Then we calculate  int(9.4) = 9.

Then  F(x) = F(9.4) = 5*9+1 = 45+1 = 46.


<U>ANSWER</U>. The fee for parking in the short-term parking garage for 8 hours and 24 minutes is 46 dollars.

Solved.
