If you purchase a calculator for $50 and save $10, what is the percentage discount given?

• A. 15%
• B. 20%
• C. 25%
• D. 30%

Answer: (C)

To find the percentage discount given on the calculator, you first need to determine the amount of the discount relative to the original price.

In this case, the calculator costs $50, and you save $10. The percentage discount can be calculated using the formula:

[

\text{Percentage Discount} = \left( \frac{\text{Discount Amount}}{\text{Original Price}} \right) \times 100

]

Substituting the values:

[

\text{Percentage Discount} = \left( \frac{10}{50} \right) \times 100 = \left( 0.2 \right) \times 100 = 20%

]

Therefore, the percentage discount given on the calculator is 20%. This means you are saving 20% off the original price of $50 when you purchase the calculator for $40 after the discount. The answer chosen correctly identifies this calculation as the discount percentage.
