PLEASE DO NOT PUT QUESTIONS IN ALL CAPS. IT BECOMES VERY ANNOYING

so anyway
she sells each shirt at a 25% discount so each shirt is (100-25)%=75% in cost

percent means parts out of 100 so
75%=75/100=7.5/10=0.75
0.75 of 12
'of' is translated to as multipy
0.75 times 12=9
each shirt costs 9 dollars

2 shirts so
2 times 9
18
18
plus tax
x=4%
4%=4/100=0.04
18 times 0.04=0.72
tax=0.72
10+0.72=18.72
total cost is $18.72
