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 9.5 percent during 1993, then fringe-benefit costs represented what percent of employment costs at the beginning of 1993 ?
Choose the correct choice.
A) 16.5% B) 8% C) 35% D) 55% E) 65%
The amount by which employment costs rose is equal to 0.035(salary costs + fringe benefit costs);   On the other hand the amount by which employment costs rose is equal to 0.03*salary costs + 0.095*fringe benefit costs;   So, 35(S+F) = 30S+95F --&gt; S = F --&gt; F/S = 1/12 --&gt; F/(S+F) = 1/(1+12) = 1/13 = 0.08.   Answer: 8%.
