Answer:

$285.12

Step-by-step explanation:

first, we'll solve for the 45% sale.

45/100

0.45 x 480

= 216

subtract from the original price

480 - 216

= 264

now we'll solve for the 8%

8/100

0.08 x 264

= 21.12

add the 45% and 8%

264 + 21.12 = 285.12

A married couple filing their federal income tax return jointly had a taxable
julia-pushkina [17]

Answer:

The income will they have left over after paying their federal income tax is <u>$64,850.00</u>.

Step-by-step explanation:

Given:

A married couple filing their federal income tax return jointly had a taxable

income of $76,300.

Now, to find according to the table the income will they left over after paying their federal income tax.

<em>So, as given in table:</em>

<em>The tax of the taxable income over $67,900 but not over $1,37,050 is $9,350 plus 25% of the amount over $67,900.</em>

As, the taxable income $76,300 falls in to the above conditions.

Now, to calculate the tax:

9350+25\%\ of\(76300-67900)

=9350+25\%\ of\ 8400

=9350+\frac{25}{100} \times 8400

=9350+0.25\times 8400

=9350+2100

=11450.

<em>Thus, the tax = $11450.</em>

Now, deducting the tax from the taxable income:

76300-11450\\=64850

<em>So, the amount left = $64,850</em>.

Therefore, the income will they have left over after paying their federal income tax is $64,850.00.

What is the sum of the first 51 consecutive odd positive integers?
Angelina_Jolie [31]
We call:

a_{n} as the set of <span>the first 51 consecutive odd positive integers, so:

</span>a_{n} = \{1, 3, 5, 7, 9...\}

Where:
a_{1} = 1
a_{2} = 3
a_{3} = 5
a_{4} = 7
a_{5} = 9
<span>and so on.

In mathematics, a sequence of numbers, such that the difference between two consecutive terms is constant, is called Arithmetic Progression, so:

3-1 = 2
5-3 = 2
7-5 = 2
9-7 = 2 and so on.

Then, the common difference is 2, thus:

</span>a_{n} = \{ a_{1} , a_{1} + d, a_{1} + d + d,..., a_{1} + (n-2)d+d\}
<span>
Then:

</span>a_{n} = a_{1} + (n-1)d
<span>
So, we need to find the sum of the members of the finite series, which is called arithmetic series:

There is a formula for arithmetic series, namely:

</span>S_{k} = ( \frac{a_{1} +  a_{k}}{2}  ).k
<span>
Therefore, we need to find:
</span>a_{k} =  a_{51}  

Given that a_{1} = 1, then:

a_{n} = a_{1} + (n-1)d = 1 + (n-1)(2) = 2n-1

Thus:
a_{k} = a_{51} = 2(51)-1 = 101

Lastly:

S_{51} = ( \frac{1 + 101}{2} ).51 = 2601

S=L (1 - r), for r
maria [59]
OK. Then let's solve for ' r '.  That means you have to come up with an equation that says     r =    everything else.

Step #1: 
Write the equation you're given:   <span>S = L (1 - r)

Let's divide each side by ' L ':      S/L = 1 - r

Subtract 1 from each side :         S/L - 1 = -r

Multiply each side by -1 :          <em>  1 - S/L = r</em>

and there you have it.
