I know this is really simple, but I am drawing a complete blank. Thanks!
Q: You have a coupon for 10% off the price of a CD. You pay $18 for a CD. How much would you pay if you did not have a coupon?
I know the answer is $20, but I cannot figure out the equation. Thank you!
Finally figured it out.
Call the normal price x.
Can you finish it from here?
