Which of the basic principles of economics is at work in the following situation? you decide how many cups of coffee to have when studying the night before an exam by considering how much more work you can do by having another cup versus how jittery it will make you feel.

The answer is: Cost-Benefits Analysis

Explanation:

A cost benefit analysis is done to identify the benefits of an action as well as the associated costs. You then subtract the costs from benefits, and if the numbers are positive you know it´s a good project. But if the costs are too big and offset the benefits, then the project is no good.

In this specific case, you have to balance the cost of drinking an extra cup of coffee (how jittery or nervous it makes you feel) with the benefits of drinking that cup of coffee (all the extra work you can do). Usually someone will keep studying and drinking coffee until they just can´t bear standing awake. It also depends on how much you really need a good grade on that specific test.

steering wheels are always situated on the left side of the car.

always drive on the right side of the road.

white lines separate lanes of traffic traveling the same direction.

hashed or broken lines means you may change lanes when it is safe.

solid white lines mean stay in your lane.

yellow lines separate traffic moving in opposing directions.

hashed or broken yellow lines mean you can carefully pass, paying attention to oncoming traffic.

never cross a solid yellow line (or double yellow line).

when turning left at an intersection, pass in front of any cars that are turning left from the opposing direction (do not try to pass behind them).

use the left lane to pass other cars traveling your direction.

do not pass in the right lane unless absolutely necessary.

if you are driving in the far left hand lane and someone would like to pass you, move over to the right lane when it is safe to do so and allow them to pass.

you must always yield to pedestrians.

come to a complete stop whenever you see pedestrians trying to cross the street.

never pass a school bus if it has flashing red lights. wait until the lights have stopped.

be aware of bicyclists. often they share the road with cars and are supposed to also follow general traffic laws.

be particularly careful about driving in cities with bike lanes -- always check before turning that a bike is not coming.

it is mandatory to pull over or stop at an intersection to allow an emergency vehicle to pass you if you see one traveling with lights flashing and/or a siren running.

do not overuse your car horn. horns are used almost exclusively for emergency situations or for when you feel unsafe.
