Hello!
The equation for an exponential deprecation model like this is 
, where a is the starting value, x is the number of years passed, and r is the amount the value deprecates each year.
We know what a and r are: a = 1600, as that is the original cost of the computer, and r = .18, as that's how much it decreases by. Substitute these two into the equation.
We get 
. Now, subtract 1 - .18 to get our final answer.
is therefore the final model.
Hope this helps!
Answer:
a) 26.3% b) 58.5%
Step-by-step explanation:
(5/19) * 100 = 26.3
(72/123) * 100 = 58.5
X= 30/r is the answer because if you divide both sides by r you are left with x=30/r because you cant divide 30 by r
