A TV has a listed price of $510.99 before tax. If the sales tax rate is 8.25%, find the total cost of the TV with sales tax incl
Trava [24]

The most appropriate choice for sales tax will be given by-

Total cost of the TV with sales tax included  is $553.15

What is sales tax?

Sales tax is a tax imposed by the government on the price of a commodity for the sale of that commodity. Imposing sales tax on a product increases the price of the product. Nowadays, sales tax has been replaced by Goods and Service Tax (GST).

Here,

Listed price of television = $510.99

Rate of sales tax = 8.25%

Sales tax to be added = \frac{8.25}{100}\times 510.99

                                     = $42.16

Total cost of the TV with sales tax included = $(510.99 + 42.16)

                                                                        = $553.15

What is the range of the function ()=12−2 f ( x ) = 1 2 x - 2 when the domain is {2, 4, 6}?
lina2011 [118]

Answer:

  {-1, 0, 1}

Step-by-step explanation:

If your function is f(x) = 1/2x -2, then the range is found by executing the function on each of the domain values:

  f(2) = 2/2 -2 = -1

  f(4) = 4/2 -2 = 0

  f(6) = 6/2 -2 = 1

The range is {-1, 0, 1}.

What is 3+0.5(4a+8)=9-2a is your solving for (a).
Nady [450]

Answer:

a = 1/2

Step-by-step explanation:

<u>Step 1:  Distribute </u>

<u />3 + 0.5(4a + 8) = 9 - 2a

3 + (0.5 * 4a) + (0.5 * 8) = 9 - 2a

3 + 2a + 4 = 9 - 2a

<u>Step 2:  Combine like terms </u>

<u />(3 + 4) + 2a = 9 - 2a

7 + 2a = 9 - 2a

<u>Step 3:  Subtract 7 from both sides </u>

<u />7 + 2a - 7 = 9 - 2a - 7

2a = 2 - 2a

<u>Step 4:  Add 2a to both sides </u>

<u />2a + 2a = 2 - 2a + 2a

4a = 2

<u>Step 5:  Divide both sides by 4 </u>

<u />4a / 4 = 2 / 4

a = 1/2

Answer:  a = 1/2
