Answer:
At the end of the 2 year, the book value of the truck is $12,600
Step-by-step explanation:
we know that
<u><em>Double declining balance method</em></u> is a form of an accelerated depreciation method in which the asset value is depreciated at twice the rate it is done in the straight-line method.
Step 1
Determine the straight-line depreciation rate
Divide the total cost by the number of years in the asset's useful life.

Step 2
Then, multiply that number by 2 and that is your Double-Declining Depreciation Rate
-----> is the depreciation for Year 1
Step 3
At the end of the first year, the book value of the truck is

Step 4
For Year 2, we will apply the same formula to the book value of the truck by the end of Year 1

-----> is the depreciation for Year 2
therefore
At the end of the 2 year, the book value of the truck is

We know that soda + hot dog =201
soda is 2x
hot dog is x
2x+x=201
3x=201
divide each side by 3
x=67
2x=134
They sold 134 sodas and 67 hotdogs
2x^2+4x+2
Carry the 2 over to the 3 behind the 4 and multiply so 2times2 is 4. So i new equation is.
X^2+4x+4
Now you have to find the factors of 4 which is 1,4 and 2,2
So now you have to see which one adds up to 4 so 1+4 is 5 so cross that out and 2+2=4.
So the two number is 2 and 2 now you have to bring down the x^2 and the signs.
(X+2) (X+2) and thats your answer
4.25(15)+4.25(1.5)(7)+0.21(1345)=
63.75+44.625+282.45=$390.825
=$390.83
The answer is C) y=-5/2x-3
