Based on the provided information, it seems that Cheris made a mistake in her steps leading to the simplification of the algebraic expression, which resulted in an erroneous final answer of 31.

Since the actual expression isn’t provided, it’s difficult to specify the exact mistake she made in her calculations. However, we can analyze some of the response options to derive the details.

1. **In step 2, should be .** - This option lacks detail but suggests an error in the expression that should have been simplified.

2. **In step 2, 16 plus 15 should be 16 times 15.** - This implies that Cheris incorrectly added when she should have multiplied.

3. **To get to step 2, Cheris should have multiplied 2 times 4 to get 8.** - This suggests she might not have correctly executed a multiplication step.

4. **To get to step 2, Cheris should have added 2 + 4 to get 6.** - This implies a basic arithmetic error if she was supposed to perform addition.

5. **No, Cheris did not make a mistake. 31 is the correct answer.** - This response defends her result as being correct.

Without the complete expression or knowledge of what steps she actually performed, I can't provide a concrete answer about what she did wrong or what she should have done differently. However, based on these options, it is likely that Cheris indeed made a mistake, and an appropriate action would be to check the operations (addition vs. multiplication) she performed in her calculations more thoroughly.

If you can provide the actual expression or the steps she took, I would be able to assist more specifically in identifying her mistake.
