Students use percents in the real world — calculating discounts at the store, tips at a restaurant, and sales tax — learning to find the percent amount and then add or subtract it from the original price.
Students will be able to…
A $40 shirt is 25% off, plus you leave a tip and pay tax elsewhere. How do you figure out what you actually pay?
Project this and switch between discount, tip, and tax. Change the price and percent to see the amount and the final total.
