Question

Determine how much time is required for an investment to triple if interest is earned at the rate of 4.25% compounded weekly(52 weeks in a year)? given the formula y=a(1+r/n)^nt

Answer 1

put
\[3=(1+\frac{.0425}{52})^{52t}\] and solve for t

Answer 2

really, 52 weeks in a year? thankfully they told us

Answer 3

can you solve this or do you need steps?

Answer 4

What satellite said (both parts).

Answer 5

I think I have this one so no steps are needed thank you

Answer 6

we go right to the answer
you solve
\[b^x=y\] by
\[x=\frac{\ln(y)}{\ln(b)}\]

Answer 7

44.85

Answer 8

so
\[52t=\frac{\ln(1+\frac{.0425}{52})}{\ln(3)}\] and
\[t=\frac{\ln(1+\frac{.0425}{52})}{52\ln(3)}\] and
