2. ** Optimal consumption: Last Friday I had two pieces of pizza, which cost $4 per slice, and four cookies, which cost $2 each. The pizza slices scored 12 and 10 on my Pleasure-o-Meter, respectively; while the four cookies scored 8, 6, 4 and 2, respectively. Did I maximise my satisfaction last Friday? Assuming I was going on another health kick the following Friday, what would I do differently?
