Calculate percent increase and decrease and explain what the percent measures.
Interpret percent change in context
Problem
Attendance rises from \(200\) to \(250\) people. Find the direction, percent change, numerical change, and original amount.
Big Picture
What this problem is really about
This response needs four connected pieces: direction, percent change, numerical change, and original attendance. We’ll identify two hundred as the starting base, subtract to find how many people were added, divide that change by the original, and convert to percent. Reporting the fields in the requested order keeps each quantity’s meaning clear.
