Question 712538: Hi, I'm Allen and I asked for assistance with this problem earlier but got no response (I don't know why questions go unanswered sometimes). Anyways, here it is again:
In the year 1900, in the country Acirema, there were 100 Lawyers and 5 million people. Every 10 years, the number of Lawyers doubles, and the population increases by 2 million. Let t be the number of years after 1900. Thus t=3 corresponds to 1903. Find the equation involving t whose solution tells you in which year 20 percent of the population are Lawyers. DO NOT SOLVE OR BEGIN TO SOLVE THIS EQUATION.
