The two real-life scenarios below represent the importance of organization in mathematics. Specifically, the importance of being able to find a percentage of an amount without a calculator. In each scenario box below, add your explanations in the spaces provided.

Scenario 1

You are in a store and want to ensure you have enough cash for an unplanned purchase. You need to be able to calculate the sales tax for your purchase without a calculator.

Part A: Identify a situation that would fit into this scenario and explain how you would organize this calculation to solve it without a calculator. Assume a 5% sales tax rate. For full credit you will need the cost of the item, an explanation of how you would calculate the sales tax, and the total cost.

Example: I am shopping for school supplies at Target, and I have $130 extra. I see air pods on sale for $120. I want to determine if I have enough money to cover the total purchase price, including tax, before I get to the register. Here’s how I would organize the problem in my head (or on paper) to get an accurate calculation…

Scenario 2

You are at a restaurant with three friends (party of 4) and need to estimate the amount of tip for your portion of the bill without using a calculator. Assume a 20% tip rate. For full credit, you will need the cost of your meal, an explanation of how you would calculate your 20% tip, and the total amount.

Part B: Explain how you would solve this problem by organizing a sample calculation.

Type your response here:

Part C: Refer back to your responses above for Parts A and B: Explain why organization was important in your thought process and calculation for an accurate solution. You should also reflect on how correct organization of a problem can help you in everyday life. Include real-world examples to support your response. Your answer should be a minimum of three sentences.
