Decide whether a residual is acceptable in context
Problem
A residual is \(\$3\). In the context of a grocery cost estimate with tolerance \(\$5\), is that acceptable?
Big Picture
What this problem is really about
Practical acceptability depends on error magnitude and context, not on whether the residual is exactly zero. Compare the absolute residual with the allowed tolerance in matching units, remembering that “up to” includes every error at or below the stated bound.
