Answer:
B. Fₙ₊₁ = Fₙ - 0.15Fₙ + 5
Step-by-step explanation:
The options above are examples of recurrence relations where the present state Fₙ₊₁ is dependent on the previous state Fₙ.
For each year that a customer does not file a claim, their rate is reduced by 15%
Fₙ-(15% of Fₙ)= Fₙ-0.15Fₙ
A credit of $5 is also awarded, therefore:
Fₙ - 0.15Fₙ + $5
Therefore If a customer did not file a claim in the nth year, the customer's rate in the (n + 1)th year as a function of their rate in the nth year is given by:
Fₙ₊₁ = Fₙ - 0.15Fₙ + 5
