<PRE><B>Question 972706</B>
The 1st 1/2 hr costs $1
There is $9 left
In terms of units:
[ dollars ] / ( dollars/hr ] = [ hrs ]
{{{ 9/1.25 = 7.2 }}} hrs
Note that
{{{ 7*1.25 = 8.75 }}} dollars
The student only has $.25 left after
7 hrs, so student cannot buy any
more time
------------------
So, the student can park for a maximum of 
7.5 hrs
