To find the percentage off, we need to calculate the difference between the original price and the discounted price, and then divide that by the original price.
Original price - Discounted price = $990 - $742.50 = $247.50.
Percentage off = ($247.50 / $990) x 100% = 25%.
Therefore, the coupon gives a 25% discount.
