cluponka [151]

Answer:

Account 1 yields greater return.

Step-by-step explanation:

Lets solve for the first formula:

$A=P(1+\frac{r}{n} )^{nt}$

First, change 6.5% into a decimal:

6.5% -> $\frac{6.5}{100}$ -> 0.065

Now, plug in the values for Account 1:

$A=3,000(1+\frac{0.065}{2})^{2(10)}$

$A=5,687.51$

<u>Now solve for Account 2:</u>

Change 6% into a decimal:

6% -> $\frac{6}{100}$ -> 0.06

Now plug in the values:

$A=3,000e^{0.06(10)}$

$A=5,466.36$

Account 1 yields better money after 10 years.
