Question 1176219
<br>
Population of Anville after n years: {{{28000e^(.05n)}}}
Population of Brinker after n years: {{{25000e^(.07t)}}}
{{{28000e^(.05t) = 25000e^(.07t)}}}
{{{28000/25000 = e^(.07t)/e^(.05t)}}}
{{{1.12 = e^(.02t)}}}
{{{ln(1.12) = .02t}}}
{{{t = ln(1.12)/.02 = 50*ln(1.12)}}}<br>
Use a calculator....<br>
Or you can simply graph the two equations on a graphing calculator and find where they intersect.<br>
