a. If you drive 14,000 miles per years, what is the total annual expense for a Toyota Corolla CE?
b. If the total annual expense for a Toyota Corolla CE is deposited at the end of each year into an IRA paying 8.5% compounded yearly, how much will be saved at the end of six years?

- 7. [10 marks] Let G = (V,E) be a 3-connected graph with at least 6 vertices. Let C be a cycle in G of length 5. We show how to find a longer cycle in G. (a) Let x be a vertex of G that is not on C. Show that there are three C-paths Po, P1, P2 that are disjoint except at the shared initial vertex and only intersect C at their final vertices. (b) Show that at least two of P0, P1, P2 have final vertices that are adjacent along C. (c) Combine two of Po, P1, P2 with C to produce a cycle in G that is longer than C.arrow_forward1.
