This is exponential decay which can be expressed as:
y=ab^t, y=final value, a=initial value, b=rate, t=time
In this case a=25000, r=(100-20)/100=0.8 so
y=25000(0.8^t), so in 4.5 years...
y=25000(0.8^4.5)
y≈$9158.93 (to nearest cent)
m=13. All you have to do is add 17 on both sides of the equation

n = 1,2,3,4....</span>
Answer:
Step-by-step explanation:
We need to rationalize the denominator of 
. For rationalizing we multiply the equation by 
So, solving
