If $3800 is invested in a savings account for which interest is compounded
quarterly, and if the $3800 turns into $4300 in 2 years, what is the interest
rate of the savings account?

Step-by-step explanation:

The formula to use for this is

For us,

A(t) = 4300

P = 3800

n = 4

t = 2

r = ?

Let's fill in what we have then:

which simplifies a tiny bit to

The first thing to do is to divide both sides by 3800 to get

Now take the 8th root of both sides (on your calculator, of course!) to get

Now subtract 1 from both sides to get

And multiply both sides by 4 to get

.0622869598 = r

Multiply by 100 to get the rate as a percentage.  It rounds to

r = 6.23%
