Answer:

2

Step-by-step explanation:

Of the $24, she has $10 left, therefore, she spent $14 on the 7 pencils.  

You can tell now how much each pencil cost, since 7 goes into 14, 2 times.

The answer is the cost for each pencil= $2.

 

However, in order to represent the problem using equations:

Assign a variable for the cost of each pencil, let x represent the cost

$24 equals 7 pencils, each x dollars worth, and the $10 left over: 24=7x+10.

Solve for x,  

                24-10=7x

14=7x

$2=x

The cost of each pencil is $2.

Farmer Company purchased equipment on January 1, Year 1 for $82,000. The equipment is estimated to have a 5-year life and a salv
aalyn [17]

Answer:

option (a) $6,240

Step-by-step explanation:

Given:

Purchasing cost of the equipment = $82,000

Estimated life = 5 years

Salvage value = $4,000

Revised expected life = 8 years

Now,

Depreciation per year = \frac{\textup{82,000-4,000}}{\textup{5}}

therefore,

The accumulated Depreciation at the beginning of year 4

= Annual depreciation × years passed

= 15,600 × 3

= $46,800

Thus,

The book value at the beginning of year 4

= Purchasing cost - Depreciation

= $82,000 - $46,800

= $35,200

Now,

The remaining life = Revised estimated life - Years passed

= 8 - 3

= 5 years

therefore,

Depreciation expense =\frac{\textup{book value at the beginning of year 4 - salvage value}}{\textup{Revised estimated life}}

= \frac{\textup{35,200  - 4000}}{\textup{5}}

= $6,240

Hence,

The correct answer is option (a) $6,240
