And DVD cost $26.75 before sale tax sale tax is 7.5% what is the total of cost of DVDs
blondinia [14]
First let's convert 7.5% into a decimal by doing Beyoncé on it and move the decimal two places to the left.

7.5\% = 0.075

Now let's multiply the cost of the DVD by the converted percent,

26.75 \times 0.075 = 2.00
Now let's add the above number to the original price, remember, $2 is not exact.

26.75 + 2.00 = 28.75

cupoosta [38]

Answer:

NPV = $ 17,200,000

Step-by-step explanation:

Total expenditures = $ 11,000,000

Net cash inflow = $ 3,000,000 per year

total duration of cash inflow = 9 years

Thus, total cash inflow = $ 3,000,000 per year × 9 years = $ 27,000,000

salvage value = $ 1.2 million = $ 1,200,000

NPV = Salvage value + total cash flow - Expenditures

on substituting the values, we get

NPV = $ 1,200,000 + $ 27,000,000 - $ 11,000,000

or

NPV = $ 17,200,000

-14(3a+6)=12(6-4a)+12 and steps please
Sunny_sXe [5.5K]

Answer:

In the given equation -14(3a+6)=12(6-4a)+12 the value of a is 28

Step-by-step explanation:

Given equation is -14(3a+6)=12(6-4a)+12

To simplify the given equation:

-14(3a+6)=12(6-4a)+12

Taking all terms to one side

-14(3a+6)-12(6-4a)-12=0

-[14(3a+6)+12(6-4a)+12]=0

Now dividing by negative sign on the above equation we get

14(3a+6)+12(6-4a)+12=0 (using distributive property)

42a+84+72-48a+12=0 ( adding the like terms )

-6a+168=0

-6a=-168

6a=168

a=\frac{168}{6}

Therefore a=28

Therefore in the given equation -14(3a+6)=12(6-4a)+12 the value of a is 28
