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!

Step-by-step explanation:
-7x -13 ≥ 8
+13 +13
-7x ≥ 21 (then, divide by -7 and when u divide by a negative number, the sign flip)
Answer: x ≤ -3
Answer: 0. 92 = 92%
100% = 500
92% = 500 × 92/100 = 460
