This is a hard question as it has a diagram.

Basically the diagram states:

Victoria - Montreal costs $580

Victoria - Saskatoon costs $230

Victoria- Toronto costs $505

Saskatoon - Toronto costs $398

Toronto - Charlottetown costs $395

Toronto - Montreal costs $189

Montreal - Charlottetown costs $250

a) Construct network matrix A for these routes.

b) Calculate A^2 and A^3.

c) How many ways can a person travel from Charlottetown to Victoria without changing planes more than once? Describe each route. Which is more economical?
