For this exercise you will create a function and store it in an include file, and then use the function in

a simple application. Open inc$-$mileage$-$functions.php and add a function named reimbursement$()$ that

will: receive a mileage amount, calculate the correct reimbursement, and return the result. The correct

reimbursement will be the mileage multiplied by $0\mathrm{.}54.$ Save this file once you have coded the function.

The mileage$-$function.html file contains a form that allows a user to submit a mileage amount to

mileage$-$function.php$.$ The mileage function.php file already contains code to receive this value. Edit

mileage function.php to: include the inc$-$mileage$-$functions.php file, send the mileage amount

submitted by the user to the reimbursement$()$ function, and receive the result that is returned. The

code already contains a print statement to print the result; the variable you use to receive the result

should match variable name used in the print statement.
