Question

review the table for a sales receipt. what is the percent of discount of the harmonica rounded to the nearest whole number percent?
harmonica $24.98
discount - $5.00
subtotal $19.98
sales tax $1.30
total $21.28

Explanation:

Step1: Use the discount percentage formula

The formula for the percentage of discount is $\text{Discount Percentage}=\frac{\text{Discount Amount}}{\text{Original Price}}\times100\%$.

Step2: Substitute the values

Here, the discount amount is $5.00$ and the original price (price of harmonica) is $24.98$. So, $\text{Discount Percentage}=\frac{5}{24.98}\times 100\%$.

Step3: Calculate the value

$\frac{5}{24.98}\times100\%=\frac{500}{24.98}\% \approx 20.02\%$.

Answer:

$20\%$
