Final answer:
To calculate the Black Friday sale, subtract the sale price from the original price, divide the difference by the original price, and then multiply by 100. Rounding to the nearest whole number, it is a 33% discount.
Step-by-step explanation:
The question is asking how to calculate the Black Friday sale percentage for a coffee maker originally priced at $49.99, which was sold for $33.55 during the sale. To find the percentage discount:
- Firstly, calculate the difference between the original price and the sale price: $49.99 - $33.55 = $16.44.
- Then, divide this difference by the original price: $16.44 ÷ $49.99 = 0.3289.
- Finally, multiply this quotient by 100 to get the percentage: 0.3289 × 100 = 32.89%.
After rounding to the nearest whole number, the Black Friday sale is 33% off the original price.
