2) Prove using strong mathematical induction: For all integers n >= 14, n cents can be obtained using 3-cent and 8-cent stamps. Solution solution is P(14): two 3-cents and one 8-cent stamps P(15): five 3-cents stamps P(16):two 8-cents stamps P(17):three 3-cent and one 8-cent stamps P(18):six 3-cent stamps P(19): one 3-cent and two 8-cent stamps P(20): four 3-cents and one 8-cent stamps P(21):seven 3-cent stamps P(22): two 3-cent and two 8-cent stamps P(23): five 3-cent and one 8-cent stamps P(24):three 8-cent stamps.
