\[18000=30788e ^{2k}\] \[\frac{ 18000 }{ 30788 }=\frac{ 30788e ^{2k} }{ 30788 }\] \[.585=e ^{2k}\]

now to get rid of e we take the natural log of both sides \[\ln .585=\ln e ^{2k}\] \[.536=2k\] then divide both sides by 2 and you get \[.268=k\]

when you plug it in you get approximately 18,000. You actually get 18,013.56 but that's only because I rounded some of the numbers off .585, .536,and .268
