Question

Answer 1

choose the best estimate ??? that means there's a list of possible answers from which to choose.

Let's go ahead and estimate this ourselves:

Round off $5691 to $5700 and $2815 to $2800. Subtracting $2800 from $5700 results in $2900. That's a good estimate.

Answer 2

5691 minus 2815 is 2876
