**Patricia**, Tuesday, February 19, 2013 at 10:47pmlet x represent one of the shirts and then set up the equation

3x-(3x*.3)=63

because there are 3 shirts and after you find the total of the shirts you would usually subtract the percentage of that total from the total. The equation equals 63 from what was given. then solve

3x-(3x*.3)=63

3x-(.9x)=63

2.1x=63

x=30

One shirt was $30
