14. Remember Shirley Sixpack and Lorraine Quiche from above? Shirley thinks a 10-ounce can of beer is just as good as two 8-ounce cans. Lorraine only drinks 8 ounces at a time and hates stale beer, so she thinks a 16-ounce can is no better or worse than an 8-ounce can. (a) Write a utility function that represents Shirley's preferences between commodity bundles com- prised of 8-ounce cans and 16-ounce cans of beer. Let X stand for the number of 8-ounce cans and Y stand for the number of 16-ounce cans. OT
