Answer:

$t=\frac{ln 3}{12ln(1 +\frac{0.07}{12})}$

t=15.74

Step-by-step explanation:

$( 1 + 0.07/12)^{12t} = 3$

Take ln on both sides

$ln(( 1 +\frac{0.07}{12})=ln 3$

move the exponent 12t before ln as per log property

$12tln(1 +\frac{0.07}{12})=ln 3$

now divide the ln on both sides to make 12t alone

$12t=\frac{ln 3}{ln(1 +\frac{0.07}{12})}$

divide both sides on both sides

$t=\frac{ln 3}{12ln(1 +\frac{0.07}{12})}$

t=15.74
