We have to express Y as a percentage.
We have this expression for Y:
[tex]Y=2(1+0.15)^2[/tex]We first solve this expression:
[tex]\begin{gathered} Y=2(1.15)^2 \\ Y=2*1.3225 \\ Y=2.645 \end{gathered}[/tex]Now, to express this as a percentage we multiply the number by 100%:
[tex]\begin{gathered} Y=2.645*100\% \\ Y=264.5\% \end{gathered}[/tex]Answer: 264.5%
