A four-door sedan costs$35000 with a residual value of $2000. Its service life is five years. Using the declining balance method

larisa [96]

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.

$\frac{\$35,000}{5}=\$7,000$

Step 2

Then, multiply that number by 2 and that is your Double-Declining Depreciation Rate

$7,000(2)=\$14,000$ -----> is the depreciation for Year 1

Step 3

At the end of the first year, the book value of the truck is

$\$35,000-\$14,000=\$21,000$

Step 4

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

$\frac{\$21,000}{5}=\$4,200$

$4,200(2)=\$8,400$ -----> is the depreciation for Year 2

therefore

At the end of the 2 year, the book value of the truck is

$\$21,000-\$8,400=\$12,600$

Answer:

Shirts = $7

Shorts $17

Step-by-step explanation:

Let:

T - shirts

S - shorts

We can make two equations out of this problem:

4T + 3S = $79

7T + 8S = $185

Through substitution we can solve for one of the unknowns. We make one equation to solve for an unknown

$4T+3S=\$79\\\\3S = \$79-4T\\\\S=\dfrac{\$79-4T}{3}$

We use the formula of S and insert it into the other equation:

$7T+8(\dfrac{\$79-4T}{3}) = \$185\\\\7T + \dfrac{\$632-32T}{3}=\$185\\\\\dfrac{\$632-32T}{3}=\$185-7T\\\\\$632-32T=3(\$185-7T)\\\\$632-32T=\$555 - 21T\\\\-32T+21T=\$555-\$632\\\\-11T=-\$77\\\\\dfrac{-11T}{11}=\dfrac{-\$77}{11}\\\\T = \$7$

Thus T-shirts are $7 each.

Now that we know T, we can use it to solve for the other unknown. You can use it on any of the formulas.

$4T+3S=\$79\\\\4(\$7) + 3S = \$79\\\\\$28+3S =\$79\\\\3S=\$79-\$28\\\\3S=\$51\\\\S=\dfrac{\$51}{3}\\\\S = \$17$

We know then that Shorts are $17 each.
