Model and analyse fixed-change finance
Let the landscaping equipment be represented by a first-order recurrence model
\(V_n\) is the equipment value, in dollars, after \(n\) years. \(V_0\) is the value at the start, so \(n\) counts the number of rule applications
\[V_n=37000-n\times 4403\]
The depreciation is a fixed percentage of the asset's initial value each year
