I got a different answer.

450 * 0.3 = 135

450 - 135 = 315

315 * 0.8 = 252

dont you mean 315 x 0.2?

**Ms. Sue**, Wednesday, January 30, 2013 at 5:56pmWe could do it this way.

315 * 0.2 = 63

315 - 63 = 252

I just saved a step in my original problem.

In other words, she had 80 percent of the money left after she spent part of it.
