1) Preferences are an important concept in economics, and they can be represented with utility functions. Let X be the consumption set, the set of all mutually-exclusive packages the programmers could conceivably produce (such as an indifference curve map without the indifference curves). The programmers' utility functions rank each package in the consumption set. If u(x) > u(g) the programmers strictly prefer x to g.
The utility function in this case isn't linear, indicating that the slope changes from one value of x to another. Note that the exponents on the utility function in this problem indicate that the programmers value X more than g. You will need to use some calculus to determine the solution to this problem numerically. You can see this by asking, for example, should I spend this next dollar on pizza or ice cream? If I spend the dollar on pizza, how much extra pizza can I get? (Let's say l/8 extra pizza.) And if I consume ...
Use of a local currency to determine preferences.
