Answer:

$766.28

Step-by-step explanation:

The equation for interest rate is as follows:

[tex]A = P(1 + r)^t\\[/tex]

A = The total amount

P = Initial amount

R = The interest rate

T = Time

Let's plug everything into the equation that is given in the question:

The initial amount = 612

Interest rate = 2.85

Time = 8 years

[tex]A = 612(1+.0285)^8[/tex]

***Just a reminder we move the decimal over twice when working with percents***

Now, lets solve for the total amount:

[tex]A = 612(1.0285)^8\\A = 612(1.252086602)\\A = 766.28[/tex]

Therefore, after 8 years the principal is $766.28.

I hope this helps!!
