D. 
Buying two $20 shirts, one with a 20% discount, and the other with a 30% discount. :)
A. 2 shirts, $ 20 each....each on sale for 50% off....so ur paying $ 20 for 2 shirts

B. 2 shirts, $ 20 each....$ 10 off.....so ur paying $ 30 for 2 shirts

C. $ 20 shirt...second shirt 0.25(20) = $ 5...so ur paying $ 25 for 2 shirts

D. 2 shirts...$ 20 each....30% discount = 0.70(20) = $ 14, 20% discount = 
    0.80(20) = $ 16...so ur paying (16 + 14) = $ 30 for 2 shirts

So the purchase with most financial responsibility is A
