How long will it take for the balance of an account to double if the savings account earns 0.75% annual interest compounded mont

Margarita [4]

You're looking for the time $t$ that it takes for the principal $P$ to double, so $A=2P$ . Dividing both sides of the formula by $P$ leaves you with

$2=\left(1+\dfrac rn\right)^{nt}$

You're given that the account earns 0.75% interest and that the interest is compounded monthly, so $r=0.0075$ and $n=12$ .

$2=\left(1+\dfrac{0.0075}{12}\right)^{12t}$
$\ln2=\ln\left(1+\dfrac{0.0075}{12}\right)^{12t}$
$\ln2=12t\ln\left(1+\dfrac{0.0075}{12}\right)$
$t=\dfrac{\ln2}{12\ln\left(1+\dfrac{0.0075}{12}\right)}\approx92.45$
