Answer: 23498.935
Step-by-step explanation:
this helped me in middle school so please remember this equation
A=P(1+R/N)NT
A=AMOUNT
P=PRINCIPAL
R=INTEREST RATE
N=NUMBERS OF TIMES THE INTEREST IS COMPOUNDED
NT=TIME(YEARS
So now we have this... right...
A=P(1+R/N)NT
you have to fill it in and you will get
a=22,150(1+3/1)^2
put that in your handy dandy calculator and you will get your answer
