Answer:
n = 1
Step-by-step explanation:
Add 20 to both sides, obtaining
n = 4 - 3n
Next, add 3n to both sides:
4n = 4
Finally, solve for n by dividing both sides by 4:
n = 1

Answer:
In 11 years
Step-by-step explanation:
To calculate the number of years it will take to depreciate to that value, we use the equation below; The amount after t years, with initial amount I at percentage of depreciation d can be represented as follows;
A = I( 1 - d)^t
In the question Using our definition, A = $8,500, I = $22,000, d = 8.5% = 8.5/100 = 0.085 and t = ?
Let’s plug these values;
8,500 = 22,000(1 - 0.085)^t
8,500 = 22,000(0.915)^t
divide both side by 22,000
8,500/22,000 = (0.915)^t
0.3864 = (0.915)^t
Taking the logarithm of both sides
log 0.3864 = log(0.915)^t
log 0.3864 = tlog 0.915
t = log 0.3864/log 0.915
t = 10.7 approximately 11 years
