Let S = spoon

Let K = knife


1 knife is thee times the cost of a spoon, so it would be 3S

Now you have 9S + 12K = 82.80

We can replace the K with 3S:

9S +12(3S) = 82.80

Simplify the left side:

9S + 36S = 82.80

Add:

45S = 82.80

Divide both sides by 45"

S = 82.80 / 45

S = 1.84

One spoon cost $1.84


We know one knife cost 3 times as much, so multiply the cost of a spoon by 3:

Knife = 1.84 x 3 = $5.52

If equipment cost $20,000 and accumulated depreciation amounts to $6,000, the book value of the equipment is?
Rina8888 [55]

The book value of the equipment is $14000

Given,

equipment cost = $20,000

depreciation amounts =  $6,000

book value of the equipment = equipment cost - depreciation cost

= 20000 - 6000

= $14000

<h3>What Are Depreciation Expenses?</h3>

Depreciation expense, on the other hand, is the amortized portion of the cost of the business's fixed assets during a certain period. Depreciation expense is recognized in the income statement as a non-cash expense that reduces the  net income or profit of the business. For accounting purposes, depreciation expense is debited and  accumulated depreciation is credited.

Depreciation expenses are treated as non-cash expenses because periodic monthly amortization is  not involved in cash transactions.

Which of the following is a area of the special trepezoid if ab=19,cd=19 and the height is 14
tankabanditka [31]

As, Opposite side of Special trapezoid is equal.So, it will be a Parallelogram.

ab=c d= 19 units

Height of Trapezoid = 14 units

Area of Trapezoid =  \frac{1}{2} \times {\text{Sum of parallel sides}} \times {\text{Perpendicular Distance between them}}

  =\frac{1}{2}\times (19+19) \times 14\\\\ =\frac{1}{2} \times 38 \times 14\\\\ = 19 \times 14\\\\= 266

So, Area of Trapezoid = 266 square units

You, can use the formula for finding the area of parallelogram,which is = Base on which perpendicular is drawn × Length of Altitude

= 19 × 14

= 266 square units
