Christie needs 54.3 Square feet of laminate wood suppose each square foot of laminated wood cost $.60 find the amount she has to
Irina18 [472]
It will cost $33.

Since wood cost $ .60 sq ft, you can assume she needs to buy 55 sq ft because she will need to buy enough to have 54.3 square ft.

55 x $ .60 = $33

$32.58 would be he total for the 54.3 sq ft and .42 cents would be for the left over .7 sq ft that she didn’t use

2х + Зу = 24<br> What is the x and y intercept
DochEvi [55]

Answer:

rearrange into y=mx+c

so it becomes

3y= -2x+24

y= (-2/3)x+24

substitute values for x

when x is 0

y is (-2/3)*0=0 +24 =24

<h2>y=24</h2>

for x intercept

0=(-2/3)*x+24

0-24=-2/3*x

-24/(-2/3)=x

<h2>x= -36</h2>

When originally purchased, a vehicle costing $23,000 had an estimated useful life of 8 years and an estimated salvage value of $
earnstyle [38]
The <u>correct answer</u> is:

$5,000.

Explanation:

When it is first purchased, the depreciation expense is calculated using the formula:

\text{Depreciation expense}=\frac{\text{Cost}-\text{Salvage Value}}{\text{Useful Life}}

The cost was $23,000; the salvage value was $3,000; and the useful life was 8 years:

\text{Depreciation Expense}=\frac{23000-3000}{8}=\frac{20000}{8}= \$2500

This means the value of the vehicle depreciates $2500 per year.

After 4 years, the vehicle would depreciate 2500(4) = $10,000.

This makes the new value $23000-$10000 = $13000.

Reevaluating the depreciation expense at this point, we use $13000 for the "cost" (current value), $3000 is still the salvage value, and now the total useful life was 6; we take 4 off of this, since it has already been 4 years:

\text{Depreciation Expense}=\frac{13000-3000}{6-4}=\frac{10000}{2}= \$5000

The depreciation expense in year 5 is $5,000.
