Calculate percent increase and decrease and explain what the percent measures.

Read percent change from a representation

Problem

A before-and-after table shows \(32\) then \(40\). What labeled percent change does it show?

Big Picture

What this problem is really about

The table establishes thirty-two as the before value and forty as the after value, while the arrow identifies the direction. We’ll subtract to find the change, divide it by the original before value, and convert that ratio to a labeled percent. Rebuilding the after value from thirty-two verifies the interpretation.
