A naïve solution for the above-stated problem is to evaluate all of the possible combinations of different pieces of varying size to find the maximum revenue-generating combination. Although this method seems the easiest and quick to practice, it has exponential time complexity. So there is a need to figure out a better method than this.

Theorem 1 (Master Theorem). Let a ≥ 1 and b> 1 be constants, let f(n) be a function f: N→ R+, and let T(n) be defined on the nonnegative integers by the recurrence T(n)= aT(n/b) + f(n). Then T(n) has the following asymptotic bounds: 1. if f(n) = O(nlogs a-E) for some constant e > 0, then T(n) = (nossa), 2. if f(n) = (nlos a) then T(n) = (nloga log n), and 3. if f(n) = N(n¹og a+s) for some e > 0 and if af (n/b) ≤df (n) for some constant d < 1 and all sufficiently large n, then T(n) = (f(n)). Use the Master Theorem above to solve the following recurrences when possible (note that not every blank needs to be filled in in every problem):
