Judy bought a coat at a 20% discount sale for $68. What was the original price of the coat?

0.8x = 68
Solve for x

Math  Ms. Sue, Tuesday, January 29, 2013 at 12:33pm
Judy paid 80% of the original price.
80% of something is 68

Okay I think I get it..
you just used the compliment to add up to 100? We are given 20%... did you say 10020=80 and then turned 80 into a decimal ?

Math  Ms. Sue, Tuesday, January 29, 2013 at 12:52pm
Yes.

Aren't u supposed to make 20 into a decimal and multiply that by 68? That's what I learned. Either I'm right or he tought my grade wrong lol
