if/elif help
Use and complete the template provided. The entire template must be completed. If you don't, your post may be deleted!

1. The problem statement, all variables and given/known data:
This is my problem for the class.

Write a script that asks for the user's age. If it is equal to or higher than 16, print a message saying that
this user is allowed to drink alcohol. If the user's age is below 16, print a message telling the user how
many years he or she has to wait before legally being allowed to drink.
As an extra, calculate how much beer an 18+ user has drunk statistically (100 liters/year) and print
this information for the user.

I can make it do the if older than 16 then you can drink
Also If you are 15 or younger than you have to wait X years until you can drink

My problem id with the calculation of how many liters you have drank since 18+.

2. Relevant commands, code, scripts, algorithms:
if/elif commands


3. The attempts at a solution (include all code and scripts):
Code:
#!/bin/bash

year=100

echo "Hello, "$USER".  This script will see if your old enough for a beer."

echo -n "Enter your age and press [ENTER]: "
read age

if  [ $age -gt 15 ]; then
  echo "You are ready for a beer!" 
  myvar2=$(expr $age + $year ) < --This is the problem
  echo "You have drank $year liters/year since you were 18 year old."
  exit 1
elif [ $age -lt 16 ]; then
  myvar=$(expr 16 - $age)
  echo "You still have to wait $myvar more years to drink sorry."
  exit 1
  
fi

lmfsetup

lmfsetup(8)						      System Manager's Manual						       lmfsetup(8)

Name
       lmfsetup - License Management Facility PAK registration script

Syntax
       /etc/lmfsetup [ template ]

Description
       The  script allows you to register data supplied by a Product Authorization Key (PAK).  The script prompts you for the data associated with
       each of the fields on a PAK.  When all the data has been entered, the License Management Facility (LMF) ensures there are  entries  against
       all  the mandatory fields, and that the Checksum validates all the license data.  If the data has been entered correctly, the PAK is regis-
       tered in the License Database.  If the data has been entered incorrectly, the appropriate error message is displayed and you are given  the
       opportunity to re-enter the data.

       The template option allows you to register license data from templates in A template containing a partially complete PAK is created by some
       products as part of their installation process.	The script only prompts you for data on the fields that are empty in the template.  If the
       script cannot find the specified template in it searches the current directory.

       The  script  is	provided as an alternative to the command.  This displays a template, which includes the fields on the PAK, and invokes an
       editor so that you can add the license data to the appropriate field.  The command also allows errors to be corrected without having to re-
       enter all the data.
