Calculate the future value of $500.20, earning interest at a rate of 3 7/8% that is compounded monthly for 4 years.

$583.92

Step-by-step explanation:

For future value use the formula

where A is future value, P is initial value, n is number of times interest is compounded per year, r is interest rate (as decimal) and t is time (in years).

In your case,

P=$500.20,

r=0.03875 (because 3 7/8%=3.875%),

t=4,

n=12.

Therefore,

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x
