C) Tradeoffs

Explanation:

A trade-off (or tradeoff) is a decision that has to be taken due to situation that involves diminishing or losing one quality, quantity or property of a set or design in return for gains in other aspects. In simple terms, a tradeoff is a situation where one thing increases while another must decrease.

Tradeoffs: Alex has found himself with only $5 to spend and must decide among the items. This illustrates the idea that scarcity forces tradeoffs.

$23,925 for both the second and third years

Explanation:

Depreciation is the systemic recognition of the cost of an asset in the profit or loss statement. It is an expense.

Depreciation may be computed on a straight line basis as

Depreciation = (cost - salvage value)/estimated useful life

Given that Matthews Band pays $65,800 for sound equipment. The band estimates it will use this equipment for four years and after four years it can sell the equipment for $2,000

Depreciation in the first year of use

= ($65,800 - $2,000)/4

= $15,950

The carrying amount at the start of the second year

= $65,800 - $15,950

= $49,850

Depreciation for the second year and 3rd year after the company realizes that this equipment will last only a total of three years

= ($49,850 - $2,000)/2

= $47,850/2

= $23,925
