Worksheet Breakdown and Solution Explanation

#### Part 1: Guided Notes
This section likely provides definitions or formulas for concepts like discounts, commissions, and sales tax. Here are the key formulas:

1. Discount:
\[
\text{Discount Amount} = \text{Original Price} \times \text{Discount Rate}
\]
\[
\text{Final Price} = \text{Original Price} - \text{Discount Amount}
\]

2. Commission:
\[
\text{Commission Amount} = \text{Sales Amount} \times \text{Commission Rate}
\]

3. Sales Tax:
\[
\text{Sales Tax Amount} = \text{Price Before Tax} \times \text{Sales Tax Rate}
\]
\[
\text{Total Price with Tax} = \text{Price Before Tax} + \text{Sales Tax Amount}
\]

#### Part 2: Problem Solving
The worksheet includes specific problems that require applying these formulas. Below are examples of how to solve typical problems:

##### Example Problem 1: Discount
- Problem: A shirt originally priced at $50 is on sale for 20% off. What is the final price?
- Solution:
1. Calculate the discount amount:
\[
\text{Discount Amount} = 50 \times 0.20 = 10
\]
2. Subtract the discount from the original price:
\[
\text{Final Price} = 50 - 10 = 40
\]
- Answer: The final price is $40.

##### Example Problem 2: Commission
- Problem: A salesperson earns a 5% commission on a sale of $800. How much commission do they earn?
- Solution:
1. Calculate the commission amount:
\[
\text{Commission Amount} = 800 \times 0.05 = 40
\]
- Answer: The commission earned is $40.

##### Example Problem 3: Sales Tax
- Problem: A book costs $25, and the sales tax rate is 8%. What is the total cost including tax?
- Solution:
1. Calculate the sales tax amount:
\[
\text{Sales Tax Amount} = 25 \times 0.08 = 2
\]
2. Add the sales tax to the original price:
\[
\text{Total Price} = 25 + 2 = 27
\]
- Answer: The total cost is $27.

#### Part 3: Fill in the Square
This section might involve completing a table or grid based on given information. For example:
- If you are given a list of prices and discount rates, you would calculate the discount amounts and final prices for each item.

#### Part 4: Investigate the Environment
This section could involve real-world scenarios or word problems. For example:
- Problem: A store offers a 15% discount on all items. If a customer buys a TV priced at $600, what is the final price?
- Solution:
1. Calculate the discount amount:
\[
\text{Discount Amount} = 600 \times 0.15 = 90
\]
2. Subtract the discount from the original price:
\[
\text{Final Price} = 600 - 90 = 510
\]
- Answer: The final price is $510.
