Velocity, a consulting firm, enters into a contract to help Burger Boy, a fast-food restaurant, design a marketing strategy to compete with Burger King. The contract spans eight months. Burger Boy promises to pay $87,000 at the end of each month. At the end of the contract, Velocity either will give Burger Boy a refund of $29,000 or will be entitled to an additional $29,000 bonus, depending on whether sales at Burger Boy at year-end have increased to a target level. At the inception of the contract, Velocity estimates an 80% chance that it will earn the $29,000 bonus and calculates the contract price based on the expected value of future payments to be received. At the start of the fifth month, circumstances change, and Velocity revises to 60% its estimate of the probability that it will earn the bonus. At the end of the contract, Velocity receives the additional consideration of $29,000. Required:
1) Prepare the journal entry to record revenue each month for the first four months of the contract.
2) Prepare the journal entry that the Velocity Company would record after four months to recognize the change in estimate associated with the reduced likelihood that the bonus will be received.
3) Prepare the journal entry to record the revenue each month for the second four months of the contract.
4) Prepare the journal entry after eight months to record receipt of the cash bonus.

Accounts Receivable (Dr.) $87,000

Bonus receivable (Dr.) $29,000

Service Revenue (Cr.) $116,000

Explanation:

Expected Value at contract inception is :

($87,000 * 8 months + $29,000) * 80% = $580,000

($87,000 * 8 months - $29,000) * 20% = $133,400

Total = $713,400

$725,000 / 8 = $89,175

The service revenue is estimated to be 116,000 if there is no probability estimate. When the expected value is incorporated the service revenue will be $89,175.

sound is invisible, but sometimes we can feel it. when a kettle-drum is thumped with a stick that time the tight drum skin moving up and down very quickly for some time and then it pumped sound waves into the air. loudspeakers also work in a similar manner.

components of a speaker:

electromagnet

in order to translate an electrical signal into an audible sound, an electromagnet is used in looudspeakers

  suspension

suspension is used to   center the voice coil in the gap of the magnet and it exerts a restoring force to keep it there. suspension is used to limits the maximum mechanical excursion of the diaphragm and voice coil.

voice coil

voice coil is a coil of wire which is attached to the apex of a loudspeaker cone. it provides the motive force to the cone by the reaction of a magnetic field to the current passing through it.

cone

in a   loudspeaker, a   thin, semi-rigid membrane attached to the voice coil, which moves in a magnetic gap due to which it vibrates   and produced sound. it is known as diaphragm and it can also be called a cone, though not all speaker diaphragms are cone-shaped.

surround

surround is also known as front suspension. surround is used to join the cone to the chassis. together with the suspension it controls the cone excursion, and it is also used to   determine how energy which is   travelling through the cone is absorbed, and how the speaker limits when it reaches the ends of its travel.

dustcap

dustcap is used to protect the voice coil from dust and dirt. it is a part of the cone.

how speaker work

the outer part of the cone is fastened to the outer part of the loudspeaker's circular metal rim. the inner part is fixed to   voice coil that sits just in front of a permanent magnet . when loudspeaker is hooked up to a stereo, electrical signals feed through the speaker cables into the coil. it will convert the coil into an electromagnet magnet . when electricity flows back and forth in the cables, the electromagnet either repels or attract the permanent magnet. this moves the coil back and forth, and it pull and push the loudspeaker cone. like a drum skin vibrating back and forth, the moving cone pumps sounds out into the air.in this way loudspeakers works.
