Find the value of x in 8.5 – { 5 ½ – [7 ½ + 2.8]/x}*4.25/(0.2)^2 = 306	Answers:  A) 3.2  B) 3.4  C) 3.5  D) 4.1  E) 4.2
8.5-{5.5-(7.5+(2.8/x))}*(4.25/0.04) = 306    8.5-{5.5-{(7.5x+2.8)/x)}*(425/4) = 306    8.5-{(5.5x-7.5x-2.8)/x}*(425/4) = 306    8.5-{(-2x-2.8)/x}*106.25 = 306    8.5-{(-212.5x-297.5)/x} = 306    (306-221)x = 297.5  x =(297.5/85) = 3.5.   ANSWER 3.5 3.5
