Answer:

$900

Step-by-step explanation:

The formula for simple interest is I = PRT where I is the interest earned, P is the principal/amount deposited or borrowed, R = rate as a decimal, and T = time in years

I = PRT

I = (500)(0.04)(20)

I = 400

Add the interest to the principal, and she will have $900 in 20 years.
