Let p (n) be the statement that a postage of n cents can be formed using just 4-cent stamps and 7-cent stamps. the parts of this exercise outline a strong induction proof that p (n) is true for n ≥ 18. a) show statements p (18), p (19), p (20), and p (21) are true, completing the basis step of the proof. b) what is the inductive hypothesis of the proof? c) what do you need to prove in the inductive step? d) complete the inductive step for k ≥ 21. e) explain why these steps show that this statement is true whenever n ≥ 18.

Aretha wanted to gather data about the cost of local bowling leagues in her area. she plotted the data and determined that the average bowling league costs consist of a one-time registration fee and a monthly fee modeled by the equation y = 15x + 20. identify and interpret the y-intercept in this model. the y-intercept is 20. this is the cost per month. the y-intercept is 20. this is the cost of registration. the y-intercept is 15. this is the cost of registration. the y-intercept is 15. this is the cost per month.
