This lesson explores consumer applications, like calculating taxes, tips, and discounts on purchases. A consumer is defined as someone who purchases goods or services from various stores. Students will learn crucial concepts including how taxes add to the purchase price, discounts subtract from it, and tips can also modify totals. Two methods for calculations—percent proportion formula and multiplication method—are introduced with practical examples. Engage with exercises to identify the type of consumer math involved and whether the final price increases or decreases.

Today’s Lesson: What: Consumer Applications Why: To solve problems involving tax, tips, discounts, etc.
What’s a consumer? A consumer is someone who __________________________ goods/ services at a variety of stores/businesses. Things for a consumer to consider are: Taxes (_____________ to the purchase) Discounts (_____________ from the purchase) Tips (________________ to the purchase) purchases add subtract add
When calculating the tax, discount, or tip, we always need to find the part out of the total for various different ________________________. There are 2 ways to do this: the percent proportion formula ( = ), OR the multiplication method (change % to a decimal and multiply). percentages
For example: You are at Target. Your total, before tax, is $28.50. If the sales tax is 6%, what is your total, including the tax? There are 2 ways to solve above problem:
Tip: Add Discount: Subtract Tax: Add $38.15 $44.21
Tip: Add Discount: Subtract Tax: Add $78.54 $6.17
Tip: Add Discount: Subtract Tax: Add $3.90 $51.92
Tip: Add Discount: Subtract Tax: Add $39.36 $9.86
