Note

Regarding Task 5 (Cover premium computation) - Instructions on github are a little bit unclear to me. Days 31-180 are discounted by {X}%, and days 181+ are discounted by an ADDITIONAL {Y}% My concern is, it's not explicitally explained if the second discount Y % should be applied to the initial base rate, or to the 'middle' base rate from days 31-180.
For example, if initial base day rate would be 100$, X=2%, Y=1%, base multiplier = 1 then:

• scenario A (discount applied to the initial base rate) - price for day 31 would be 100 * (1 - 0.02) = 98$, and price for day 181 would be 100 * (1 - (0.02 + 0.01)) = 97$
• scenario B (discount applied to the 'middle' base rate) - price for day 31 would be 100 * (1 - 0.02) = 98$, and price for day 181 would be 98 * (1 - 0.01) = 97.02$

In my solution, I decided to choose scenario A, as it was already implemented in the code before and seems more straightforward. In case I would like to implement scenario B, I would only adjust one line: var after150DaysRate = after30daysBefore180DaysRate * (1.00m - (coverMultiplier.After150DaysDiscount)); in Claims\Domain\Services\PremiumCalculator.cs
