**Part**: The specific quantity you want to find the percentage of.**Whole**: The total quantity.

[

\text{Percentage} = \left( \frac{45}{60} \right) \times 100 = 75%

]

[

\text{Savings} = 50 \times 0.30 = 15 \text{ dollars}

]

### 2. Tax Calculations

Sales taxes can vary, and calculating them can sometimes lead to confusion. Suppose you’re purchasing a set of items costing $100 and the sales tax is 8%. The total amount you will pay can be calculated as follows:

[

\text{Tax Amount} = 100 \times 0.08 = 8 \text{ dollars}

]

[

\text{Total Price} = 100 + 8 = 108 \text{ dollars}

]

Percentage calculations are crucial when dealing with savings accounts or loans. If a bank offers a 5% interest rate on a savings account with $1,000, the yearly interest accrued would be:

[

\text{Interest} = 1000 \times 0.05 = 50 \text{ dollars}

]
