This document presents a group problem for students to solve. Raj must choose between two payment methods: 1) a 6% commission on all sales or 2) a $300 base salary plus 2% commission on any sales over $4,000. Students are asked to calculate Raj's pay under both methods if he sells $5,000 or $10,000, and recommend the better option along with factors for Raj to consider. Separate examples are given on straight and differential piecework payment systems. The document concludes with reading and question assignments.
