How much money did Marsha earn in interest? What would be her new account balance?

$2058

Assuming the interest is compounded annually, you would multiply $9500 by 1.04 (to add the 4%). Then repeat this process by multiplying the result by 1.04 for a total of 5 times. (1 for each year)

Subtract the new total from the original $9500 and you get the amount earned through the interest.

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
