We have a project for Economics, and we need to advertise something that consumers will be willing to buy. My group thought of "improved" hand sanitizer. So, instead of it killing 99.9% germs, we would make it kill 100% germs. Although, we are having a hard time trying to prove that our hand sanitizer can, but we can't change what our product is anymore, since we only have a couple more weeks until we pass the commercial.
Can anyone help us? Thank you in advance.
