Objective and Summary:
SWBAT solve discount problems by using both visual and arithmetic solutions

MPPP, Part 2--Ms. Paul's Pantalones Palace also sells jeans. The True Blue jeans usually sell for $33, but the Fall Sale has all pants for \frac{1}{3} off the original price.

Use both a visual and arithmetic model to find the final discounted price of a pair of True Blue jeans.
You must use the Formative SYW.

"The final price of True Blue jeans is..."

CFS:

MEDIUM Problems

Huge Discounts--On Friday only, Kohl's has a discount on all fashion items for \frac{2}{5}
off the original price.

Some Prize-approved khaki pants are normally $36. What would the final price be after taking \frac{2}{5}

Challenge problem. Try if you have time

Concert--Mr. Mancini will be singing at the SAP Center in October. Mr. Figueroa bought a ticket the day they came out for $25.

Mr. Figueroa decides that he can make a lot of money by selling the ticket at a higher price (markup).
He marks it up by 1/4 of the original price he paid and sells it to Mr. Hwung.

What is the final price Mr. Hwung paid? Use a visual to find the higher price.

Video Games--Math Stop has sales on a variety of math-related video games.
This week only, the videogame Modern Mathematicians 2 is being sold for \frac{1}{3}
off its original $327 price. What is the final (discounted) sales price?

CFS:
#1: Uses an appropriate visual support
#2: Accurately calculates markdown and final price
