Antonio would like to replace his golf clubs with a custom-measured set. A local sporting goods megastore is advertising custom clubs for $710, including a new bag. In-store financing is available at 5.22 percent, or he can choose not to renew his $600 certificate of deposit (CD), which just matured. The advertised CD renewal rate is 5.58 percent. Antonio knows the in-store financing costs would not affect his taxes, but he knows he'll pay taxes (25 percent federal and 5.75 percent state) on the CD interest earnings. Should he cash the CD or use the in-store financing? Why?

Antonio and Replacement of Golf Clubs

a. He should cash the CD and use the proceeds to finance part of the golf clubs.

b. The reason is that he would pay more in in-store financing totaling $37.06 per annum than the net interest he would generate from the CD totaling $23.18 per annum.  And Antonio would incur a net loss of $13.88 if the CD was renewed unlike the $5.74 if the CD were not renewed.

Explanation:

Option 1: Renew Certificate of Deposit (CD):

Interest earned  = $33.48 ($600 * 5.58%)

Taxes                  =   10.30 ($33.48 * 30.75%)

Net Income         = $23.18

Cost of in-store financing = $37.06 ($710 * 5.22%)

Net Loss(overall) = $13.88 ($37.06 - $23.18)

Option 2:

Sale-off of CD = $600

Net financing required = $110 ($710 - $600)

Cost of financing = $5.74 ($110 * 5.22%)

answer; /// i believe the correct answers are (b) change in population and (e) future expectation of check first, good luck

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.
