This document provides instructions for a team assignment involving equations and percentages. Students are asked to complete two Excel cases that apply concepts from chapters 5 and 6 of their text. The cases involve calculating percentages and equations to determine painting costs. For the first case, students calculate total square footage needing paint and gallons of paint required. For the second case, students calculate labor costs, profit margin, and final bid price for a painting job based on square footage, labor rates, and a desired profit margin.
