The question you posted seems incomplete. You posted the set up information, but the actual question itself is missing. I'm assuming you want to find which is the better deal? If my assumption is correct, then go ahead and read on. If my assumption is incorrect, then you can ignore this post.

Solution:
The percent 30% converts to 0.30 when we move the decimal point two spots to the left. Note how 30% = 30/100 = 0.30
So saying 30% of 63 means 0.30*63 = 18.90, which is the amount of money we save. This value is smaller than the $22 rebate amount so that means Coupon B is the better deal.
We can see that if we go with Coupon A, then the final price will be 63-18.90 = 44.10; if we go for Coupon B, then the final sale price is 63-22 = 41. This is further confirmation that choice B is better.
Be careful though: The $22 rebate means that you'll have to mail (or possibly email) some kind of proof of purchase form/card. A bit of time will pass by until you can get the $22 in the mail. Some companies probably offer some kind of direct deposit. A rebate is basically a partial refund that acts more or less like a discount, but it's not an immediate discount. In short, you will not save the $22 right away and instead you'll be expected to pay the full $63 for the shoes when you're at the checkout counter. So if you want to save money right away, then go for option A. However, I still think option B is the better choice in the long run. Of course, it will depend on how long you're willing to wait for that savings.
