Tema [17]

The preparation of the Sales section of the income statement for Blue Spruce Corp. is as follows:

BLUE SPRUCE CORP.

<h3>Income Statement</h3>

For the year ended October 31, 2022

Sales Revenue                         $908,400

Sales Returns and Allowances  (20,900)

Sales Discounts                           (14,700)

Net sales revenue                  $872,800

<h3>How makes up the net sales revenue?</h3>

The net sales revenue represents the gross revenue minus sales returns and allowances and sales discounts.

In most jurisdictions, the sales discount account is reported on the income statement as a contra revenue account.  This implies that sales discounts are directly deducted from the gross sales and do not appear in the expense section nor the notes to the sales or revenue.

<h3>Data and Calculations:</h3>

Sales Revenue $908,400

Freight-Out $12,600

Sales Returns and Allowances $20,900

Sales Discounts $14,700

Thus, the preparation of the sales section of the income statement for Blue Spruce Corp. shows a net sales revenue of $872,800.

A total of 679 tickets were sold for the school play. they were either adult tickets or student tickets. there were 71 fewer stu
guapka [62]
For example a stands for the number of adult tickets, and s stands for the number of student tickets.

Write a system of equation based on the problem
An equation for "<span>A total of 679 tickets were sold for the school play"
</span>∴ a + s = 679 <em>(first equation)</em>
An equation for "<span>there were 71 fewer student tickets sold than adult tickets"
</span>∴ s = a - 71 <em>(second equation)</em>
<span>
Find the solution of the system
Subtitute s with a - 71 in the first equation to find the value of a
a + s = 679
a + a - 71 = 679
2a - 71 = 679
2a = 679 + 71
2a = 750
  a = 750/2
  a = 375
The number of adult tickets sold is 375</span>

4(-3)(-2)<br> How do<br> I do this?
Fiesta28 [93]

Answer:

4(-3)(-2) = 24

Step-by-step explanation:

first solve the numbers in parenthesis.

4(-3)(-2)

= 4(6)

the negative sign cancels out in the product, because both of the numbers you multiplied are negative, which makes the product positive.

now solve for 4(6).

4(6) = 24

DaniilM [7]

J=15b/10g

S=21b/g w/ the ratio 3/2 (15/10=3/2)

1) Form an equation (21/g=3/2).

2) Since you are trying to find the denominator, multiply 3/2 so that the numerators are the same (3×7=21 2×7=14).

3) The answer will be whatever the denominator is at the end.

The answer is there are 14 girls in Steven's class.
