Final answer:
Clare received a 40% off with her coupon.
Step-by-step explanation:
To find the percent off Clare received with her coupon, we need to calculate the discount amount first. The discount amount is the difference between the original price and the price Clare paid. In this case, the discount amount is $82.50 - $49.50 = $33. To find the percent off, we divide the discount amount by the original price and multiply by 100: $33 / $82.50 * 100 = 40%.
