Final answer:
Janet received b. 60% discount on the candle. This was calculated by subtracting the sale price from the original price, then dividing by the original price and multiplying by 100.
Step-by-step explanation:
The student is asking about how to calculate the percent of the discount that Janet received when she purchased a candle. To calculate the discount percent, you can use the formula:
Discount Percent = (Original Price - Sale Price) / Original Price × 100.
In Janet's case, the original price of the candle was $15.00, and she purchased it for $6.00. The discount amount is $15.00 - $6.00 = $9.00. Now, we can calculate the percent of the discount by inserting the values into the formula: ($15.00 - $6.00) / $15.00 × 100 = $9.00 / $15.00 × 100 = 60%.
Therefore, the answer is b. 60%.
