Then he should sell all of them for 3 dollars and he'll get $450 dollars from all 150 t-shirts
The answer is 119.8245. 49% of $234.95 is 115.1255 (.49 • 234.95 = 115.1255). Subtract $115.1255 from $234.95 to get the answer to get 119.8245 (234.95 – 115.1255 = 119.8245).
The first option is the correct choice of answers.
I'm pretty sure that the answer is 12C4 = (12p4)/4! = (12*11*10*9)/4*3*2*1 = 495
Hope this helps
