AIM: How can we find percents of amounts?
HW: Enjoy the weekend
A shirt is regularly priced at $20. It is on sale for 30% off. If the NYC sales tax is 8.875%, how much will the shirt cost after the discount, tax included?
Classwork: Today was a continuation of finding percents of amounts. We learned another approach that doesn't require the use of proportions. Students learned that if they want to find the percent of an amount, they can convert the percent to a decimal (by moving the decimal two places to the left) and then multiply that decimal by the amount they are trying to find the percent of.
Example: $180.00 item is 40% off. How much is the discount? ---> 40% = .40 ----> 180 x .40 = $72. The discount is $72.
We practiced several scenarios using this new shortcut method. We practiced applying it in the context of tax, tip, and discount.
