wolverine [178]

Answer:

1100 cookies

Step-by-step explanation:

There are 3 types of cookies, the first represents 45% of the total, the second 25% and the last type there are 330. We can pose the following equation:

0.45 * x + 0.25 * x + 330 = x

solving for x:

x - 0.45 * x - 0.25 * x = 330

0.30 * x = 330

x = 330 / 0.3

x = 1100

which means that there are a total of 1100 cookies

A company uses the declining-balance method of calculating depreciation expense. On January 1, the company buys machinery for $7
NeX [460]

Answer:

$516,000

Step-by-step explanation:

Given:

- Beginning boo value of asset A = $750,000

- The salvage value of the asset B = $100,000

- The estimated life of asset t = 10 years

Find:

What is the book value in year 3?

Solution:

- Under the declining balance method, double declining method depreciation rate (R) is calculated by:

                                  R = 1 / t

                                  R = 1 / 10 = 10%

- The accumulated depreciation for 3 years is as follows:

                                 Depreciation: ( A - B ) * R * 2

                 Year 1:     DDB = ( 750,000 - 100,000 ) * 0.2 = $130,000

                 Year 2:    DDB = ( 620,000 - 100,000)*0.2 = $104,000

- The book value in year 3 is:

                                 $ 620,000 - $104,200 = $516,000
