Melissa and Dale each have $23.00 each to spend at a book fair, where all students receive a 15% discount. They both want to purchase a copy of the same book, which normally sells for $24.50 plus 10%
sales tax
Part A: For Melissa, she takes 15% of $24.50 and subtracts that amount from the normal price. She takes 10% of the discounted selling price and adds it back to find the purchase amount. Show your work to
see what the final price would be for Melissa-does Melissa have enough money to buy the book? (4 points)
Part B: For Dale, he takes 85% of the normal purchase price and then computes 110% of the reduced price. Show your work to see what the final price would be for Dale-does Dale have enough money to
buy the book? (4 points)
Part C. What do you notice about their results? Do you favor one way to work the problem over another? Why or why not?
