If a problem says the starting amount is 20 and the change is -4, which quantity would be 16?

Explanation:
When you have a starting amount and a change, you apply that change to the starting amount to get the final amount. Here, start with 20 and apply a change of -4, which means subtract 4: 20 + (-4) = 16. The quantity that ends up being 16 is the result quantity—the final amount after the change. The starting quantity (or beginning quantity) would be the initial 20, and the change quantity is the -4.
