According to surveys at a company, 20 percent of the employees owned cell phones in 1994, and 60 percent of the employees owned cell phones in 1998. From 1994 to 1998, what was the percent increase in the fraction of employees who owned cell phones?

A. 3%
B. 20%
C. 30%
D. 200%
E. 300%

The fraction of employees who owned cell phones in 1994 was 20/100 = 1/5, and the fraction of employees who owned cell phones in 1998 was 60/100 = 3/5. Thus, the question becomes "3/5 is what percent greater than 1/5?". To answer this question, we can use the percent greater formula, which is [(new value - old value)/(old value)] * 100.

\(\Rightarrow\) Percent Greater = [(new value - old value)/(old value)] * 100

\(\Rightarrow\) Percent Greater = [(3/5 - 1/5)/(1/5)] * 100

\(\Rightarrow\) Percent Greater = [(2/5)/(1/5)] * 100

\(\Rightarrow\) Percent Greater = [2/5 * 5/1] * 100

\(\Rightarrow\) Percent Greater = 2 * 100 = 200%

Answer: D
