Ky wants to buy three shirts, which were originally priced $49.96 each. the store will discount the price of the third shirt and then apply a 7.1% tax total of all three shirts. including tax what will be the mean cost of each shirt

Buy two and get 3rd one 50 off
So 
49.96+49.96+24.98=124.9*.071=8.8679(Tax) now add 124.9+8.8679=133.7679
<49.96(.50)>=24.98
7.1/100==.071
Each Shirt cost
49.96*.071=3.54716 add the cost of shirt 49.96=53.50716 total mean of shirt 
49.96*.071= above cal. 53.50716 total mean of shirt 
24.98*.071=1.77358+24.98=26.75358 total mean

I really hope this helps!
