Answer
Erin had 633 stamps at the end of 2022.
Solution
- Initially, Erin had \( 276 \) stamps.
- At the end of 2021, she added \( 113 \) stamps, so her collection became:
\[
276 + 113 = 389
\]
- At the end of 2022, she added another \( 244 \) stamps, so her collection became:
\[
389 + 244 = 633
\]
- Therefore, at the end of 2022, Erin had \( 633 \) stamps.

To find out how many stamps Erin had at the end of 2022, we can start with her initial count and add the stamps she collected over the two years. She began with 276 stamps and added 113 stamps in 2021 and then 244 stamps in 2022. So, the calculations would be: 276 (initial stamps) + 113 (2021 additions) + 244 (2022 additions) = 633 stamps. At the end of 2022, Erin had a total of 633 stamps in her collection!
