Lyle Wants to Buy a New CD System

Lyle wants to buy a new CD system. Every week he cashes his paycheck and deposits part of it into a coffee can at home. Sometimes, though, he is unable to put anything away for the CD system because he spends the money on movies, pizza, clothes, and other things that he likes but doesn't really need. In this example, the long-term reward is

A) his paycheck.
B) the money he spends on movies, pizza, and other things.
C) the purchase of the CD player.
D) all of the above
E) none of the above
