I don't want the answer to this question, but if someone could please tell me how to work it out, that would be great and I could finish it on my own.

Question

Thank you very much:)

Question-
Your station charges $15.95 for an oil change. As a promotion you sell six coupons for oil changes for $80. What percentage discount are you offering for customers who purchase the 6-coupon book?

Answer 1

divide the $80 by 6 to see how much each oil change costs with a coupon.

So, you want to find out what percentage the discount is of the retail price of $15.95.

So, subtract the coupon price from the retail price to get the savings, then divide that by the retail price.

And, of course, multiply by 100 at the end to convert a decimal value to %!
