An initial investment of $480 earns interezt for 7 years in an account that earns 13% interest, compounded quarterly. find the amount of money in the account at the end of the 7 year period

$1,175.34

Step-by-step explanation:

To solve for the total amount after 7 years. We need to use the formula:

Let's first break down all the variables that we have.

P = 480

r = 13% or 0.13

n = 4 (Quarterly)

t = 7 years

Now we simply substitute the values into the formula.

The account will have $1,175.34 after the 7 year period.

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

24 units
