The photos at the top is the format I am trying to follow.

Using the analytical hierarchy process, create a pair-wise comparison matrix (preference table), average preference table, and overall preference table. I have 4 criteria for comparison which are cost, speed of service, taste, and online access ability.

Ranking of importance

cost - 1

speed of service - 5

taste - 7

online access - 2
