log of both sides..

log2=2t log(1+.035)

can you do that? Solve for t?

**Reiny**, Thursday, February 19, 2009 at 9:39amyou want the $2700 to double, so A = 5400

5400 = 2700(1 + .035)^(2t)

2 = 1.035^(2t)

I hope you know how to use logs and know the rules of log operations

2t = log 2/log 1.035

2t = 20.148

t = 10.07

= 10.1 to the nearest tenth
