This Application Problem is a part of the Lesson 26, Unit 7, Grade 2. Judy bought an MP3 player and a set of earphones. The earphones cost $9, which is $48 less than the MP3 player. How much change should Judy get back if she gave the cashier a $100 bill? This two-step problem encourages students once again to use the RDW process and make a tape diagram to visualize the relationships within the problem and correctly identify the question being asked.
