Yesterday, Pete had 14 shirts. Today, he donated n shirts. Using n, write

an expression for the number of shirts Pete has left.

14 - n.

Step-by-step explanation:

If he donated 'n' shirts, we can simply subtract 'n' from his initial amount of shirts, which is stated as '14'. Therefore:

'14 - n' is an expression that can represent how many shirts are remaining after he donated them.
