A survey of employers found that during 1993 employment costs rose 3.5 percent, where employment costs consist of salary costs and fringe-benefit costs. If salary costs rose 3 percent and fringe-benefit costs rose 5.5 percent during 1993, then fringe-benefit costs represented what percent of employment costs at the beginning of 1993 ?	Choose the correct choice from the following answers
A) 16.5%	B) 20%	C) 35%	D) 55%	E) 65%
In my view easiest method would be, eliminating the percentage sign   Let 3.5 be 35   5.5 be 55   and 3 be 30   then first eq: S+F=E   130S+155F=135E   5s=20F   therefore, s=4F and then E=5F   F/E=F/5F=20%   Therefore, Answer is 20%
