I am a little bit confused by what it is asking in terms of choosing the correct method, so I will work through it and hope it answers your question, or comment and we can work through it together.
Original price = $65
Sale = 15%
Discount = $10
Take the sales price off first. There's a few ways to do this. You can multiply by the 15% and then subtract, or you can multiply by 85% because that is what would be left. Personally, I would do 85% because it is easier.
65 * 0.85 OR 65 *
55.25
Then subtract the $10 :
55.25 - 10
45.25
This is what you would pay. To find the percentage of the original price, we will plug in the new number over the old number, and then multiply by 100%:
