Answer :
For a initial amount invested P at an annual interest rate r, after t years the total amount will be:
[tex]T=P\cdot(1+r)^t[/tex]Then, the interest is given by:
[tex]I=T-P[/tex]For P = $134,000, t = 2 years and r = 7%, we have:
[tex]\begin{gathered} T=134000\cdot(1+0.07)^2 \\ T=\text{ \$153,416.60} \\ I=T-P=153,416.60-134,000=\text{ \$19,416.60} \end{gathered}[/tex]
