We can hust give the funtion numbers firectly:
You have 20 cheese!
You have 30 boxes of crackers1
Man that's enough for a party!
Get a blanket.

OR,we can use variables from our script:
You have 10 cheese!
You have 50 boxes of crackers1
Man that's enough for a party!
Get a blanket.

We can even do math inside too:
You have 30 cheese!
You have 11 boxes of crackers1
Man that's enough for a party!
Get a blanket.

And we can combine the two,variables and math:
You have 110 cheese!
You have 1050 boxes of crackers1
Man that's enough for a party!
Get a blanket.
