Large box 70, small 55
x+y=125
40x+20y=3900
y=125-x
40x+20(125-x)=3900
40x+2500-20x=3900
20x=1400
x=70
125-70=y
y=55

Explanation:
since you are buying five shirts for nine dollars each you would need to do 5x9 which equals 45. Now you need to do 12x2 since you bought two pairs of pants for twelve dollars each. 12x2 equals 24. Now you need to add 24 and 45 to see what your price is. 24+45=69. Now add on four dollars for shipping and handling and you will have $73 dollars. Hope this helps!
