Hello
To solve this question, we should use the formula of compound interest and calculate the principal
[tex]\begin{gathered} A=p(1+\frac{r}{n})^{nt} \\ A=300000 \\ r=8\text{ \% = 0.08} \\ t=17 \\ n=2 \\ p=\text{ ?} \end{gathered}[/tex]Let's solve for p
[tex]\begin{gathered} a=p(1+\frac{r}{n})^{nt} \\ 300000=p(1+\frac{0.08}{2})^{2\times17} \\ 300000=p(1+0.04)^{34} \\ 300000=p(1.04)^{34} \\ 300000=p\times3.794 \\ p=\frac{300000}{3.794} \\ p=79072.2 \end{gathered}[/tex]From the calculation above, the principal or what they need to invest P79,072.2 now to get P300,000
