Estimate a contextual quotient or percent with a specified benchmark
Problem
A \(\$58\) jacket is \(17\%\) off. Use \(\$60\) to estimate the savings, then compare the estimate with \(\$15\).
Big Picture
What this problem is really about
A percent discount is a fraction of the price, not a dollar amount by itself. We’ll apply seventeen percent to the specified sixty-dollar benchmark, either as a decimal or as familiar percent parts, and then compare the estimated savings with fifteen dollars. That places the estimate on the correct side of the midpoint.
