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,

x -

median = 1.25

range = 12-14.5

interquartile = q12-q14.5

y -

median = 1

range = 15-17

interquartile = q15-q17
