Understanding the Problem
To find the final sale price after taking a 15 percent discount off of $68, we need to calculate the amount of the discount and then subtract it from the original price. Discounts are a common way for businesses to offer customers a reduced price on a product or service, and understanding how to calculate them is an essential skill in mathematics.
Calculating the Discount Amount
The first step in calculating the discount amount is to find 15 percent of the original price of $68. To do this, we can multiply the original price by the discount percentage (0.15). The formula for this calculation is:
Discount Amount = Original Price x Discount Percentage = $68 x 0.15 = $10.20
Calculating the Final Sale Price
Now that we have the discount amount, we can subtract it from the original price to find the final sale price. The formula for this calculation is:
Final Sale Price = Original Price - Discount Amount = $68 - $10.20 = $57.80
Comparing the Answer Choices
Now that we have calculated the final sale price, we can compare it to the answer choices to see which one is correct. The answer choices are:
A. $57.80 B. $58.20 C. $57.80 D. $56.50
Based on our calculation, the correct answer is A. $57.80 and C. $57.80.
Conclusion
In this problem, we used the formula for calculating a discount amount and then subtracted it from the original price to find the final sale price. We compared our answer to the answer choices and found that the correct answer is A. $57.80 and C. $57.80. This problem demonstrates the importance of understanding how to calculate discounts in mathematics.
