Elijah Flynn · Answer 1

Joanne could have rounded her answer to a specific decimal place, rather than using the exact answer. If you use a rounded answer to verify your solution, you may get a statement that is not exactly equal. The numbers, 12.34 and 12.33 are very close to each other, so Joanne can assume she solved the multistep equation correctly.
