Katie and Margarita have $20.00 each to spend at Student Choice bookstore, where all students recieve a 20% discount. They both want to purchase a copy of the same book which normally sells for $22.50 plus 10% sales tax.
Write an expression to find the total cost of the book with tax and the discount.
Margarita wants to figure out if she has enough money. She finds 80% of the normal price and then computes 110% of the reduced price.
Is margarita correct? Will this give her the cost with tax and the discount? Explain.
Do they have enough money to purchase the book? How do you know?
