John has only $4.00 cash.

John is out of milk.  John’s son wants milk.  A gallon of milk costs $3.79.  The closest store is one mile from John’s house.

John’s car is almost out of gas.  John’s car has one mile to empty.  A gallon of gas costs $3.85.  The closest gas station is at the store that is one mile from John’s house.

If John drives to the store/gas station one mile from his house to buy a gallon of milk for his son, and John has to use his only $4.00 to buy a gallon of gas to get back home,  will:

a.)  John’s son keep him up all night because he did not have milk?

b.)  John downsize to a smaller car with better gas mileage and lose a large amount of money on the trade-in of his car?

c.)  John by a cow?

d.)  John begin to commute on his bicycle, lose more sleep because of the extra time needed to bike, become tired and cranky causing undo stress on his life, marriage, and son?

e.)  All of the above?

You decide!
