Find a percent of a quantity and interpret the result in context.
Choose a smart percent-of-quantity strategy
Problem
Use the benchmark-percent strategy \(15\%~=~10\%~+~5\%\) to find \(15\%~\text{of}~80\) snack packs. Give the strategy label and result.
Big Picture
What this problem is really about
The task requires the benchmark-percent strategy, so fifteen percent should be split into ten percent and five percent of the same whole. We’ll find one tenth of eighty, halve that amount for five percent, and add the two parts. Keeping snack packs attached also makes the strategy label and contextual result easy to verify.
