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

25^(n-3)=5^(n+8)
Remember: 25=5²
Therefore:
5^[(n-3)²]=5^(n+8)
5^(2n-6)=5^(n+8)
Then:
2n-6=n+8
2n-n=8+6
n=14
Answer: n=14
I can’t see the bottom numbers
Here is the answer
I can’t seem to do the symbols here so the answer is in the picture.
It is given in the question that,
A flower garden has 12 sunflowers for every 45 irises.
And we have to find the unit rate for the number of irises per sunflower.
And for that we have to divide number of Irises by number of Sunflower. That is

And that's the required unit rate .
