You save $8,500.00. You place 40% in a savings account earning a 4.2% APR compounded annually and the rest in a stock plan. The stock plan decreases 3% in the first year and increases 7.5% in the second year. What is the total gain at the end of the second year for both accounts combined?

Answer:

The total gain at the end of the second year for both accounts combined is $509.09.

Step-by-step explanation:

Amount saved = $8500

40% of 8500 is saved in saving account; [tex]0.4\times8500=3400[/tex]

Remainder amount in stock plan; [tex]8500-3400=5100[/tex]

Working for savings plan:

[tex]A=p(1+\frac{r}{n})^{nt}[/tex]

Here, p = 3400 ; n = 1 , t = 2 , r = 0.042

Putting values in formula:

[tex]A=3400(1+\frac{0.042}{1})^{2}[/tex]

[tex]A=3400(1+0.042)^{2}[/tex]

A = $3691.60

We get a gain of [tex]3691.60-3400=291.60[/tex] dollars

Working for stock plan:  

The stock plan decreases 3% in the first year and increases 7.5% in the second year.

[tex]5100\times 0.97=4947[/tex]

When increases;

[tex]4947\times1.075=5318.03[/tex]  dollars

So, we get a gain of [tex]5318.03-5100=218.03[/tex] dollars  

Therefore, we have a total gain of [tex]291.06+218.03=509.09[/tex] dollars.
