Lesson 4 Ex1 Work Backward SHOPPING Lucy and Elena went to the mall. EACH girl bought a CD for $16.50, a popcorn for $3.50, and a drink for $2.50. TOGETHER, they had $5.00 left over. How much money did they take to the mall? They had $5 left. UNDO the 2 × $2.50 spent on drinks = 10 UNDO the 2 × $3.50 spent on popcorn = 17 UNDO the 2 × $16.50 spent on CDs = 50 So, Lucy and Elena initially had $50.
