PLZ help me !!

May 27th, 2006

I have to submit the assignment tomorrow i got stuck in something looks silly the question is:
parking garage charges a $2.00 miniumum fee to pack for up to three hours.
The garage charges an additional $0.50 per hour for each hour or part thereof
in excess of three hours. The maximum charge for any given 24-hour period is $10.00.
Assume that no car parks for longer than 24 hours at a time. Write a program that
calculates and prints the parking charges for each of three customers who parked
their cars in this garage yesterday. You should enter the hours parked for each customer.
Your program should print the results in a neat tubular format and should calculate
and print the total of yesterday’s receipts. The program should A parking garage charges
a $2.00 miniumum fee to pack for up to three hours. The garage charges an additional
$0.50 per hour for each hour or part thereof in excess of three hours. The maximum charge
for any given 24-hour period is $10.00. Assume that no car parks for longer than 24 hours
at a time. Write a program that calculates and prints the parking charges for each of
three customers who parked their cars in this garage yesterday. You should enter the hours
parked for each customer. Your program should print the results in a neat tubular format
and should calculate and print the total of yesterday’s receipts. The program should use
the function calculateCharges to determine the charge for each customer.

and my solution is

the problem that when the time is shown it has to be only with one decimal point not to decimal points for example if it is 2.40 i need it to be 2.4

Help me plz
