Compute the payback period for each of these two separate investments: A new operating system for an existing machine is expected to cost $240,000 and have a useful life of five years. The system yields an incremental after-tax income of $69,230 each year after deducting its straight-line depreciation. The predicted salvage value of the system is $9,000. A machine costs $170,000, has a $13,000 salvage value, is expected to last nine years, and will generate an after-tax income of $38,000 per year after straight-line depreciation.

Investment                               Payback period(in years)

A                                               2.08

B                                               3.066

Explanation:

The payback period is the length of time in years it will take the net cash inflow of a project to recoup its initial cost

Payback period = Initial cost of investment /Annual net cash inflow

Investment A

Annual depreciation = (Cost - Salvage value)/Number of years

                               =  (240,000 - 9,000)/5 =

Annul cash inflow = 69,230 + 46200  = 115,430

Payback period = Initial cost of investment /Annual net cash inflow

                           = 240,000/ 115,430 = 2.079

Investment B

Annual depreciation = (Cost - Salvage value)/Number of years

                               =  (170,000 - 13,000)/9 = 17,444.444

Annul cash inflow= 38,000 + 17,444.44= 55,444.44

Payback period = 170,000 /55,444.44  =3.067

Investment                               Payback period(in years)

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.
