Frank had a pretest score of 6, what must his posttest score be for his percent of increase to be 50 percent?

Was the pretest score 6% (6 out of 100)?
No my teacher said he thought it was like 6 out of 20
50% * 6 = 3
6 + 3 = 9
6 + 3 = 9
Ohhhh ok I get it now.....so if you had a percent of decrease problem you would to the same thing but divide right?
No, you'd still multiply, but subtract 3 from 6. A decrease of 50% would be 3.
