Answer:
x ≤ 205.05
Step-by-step explanation:
x = dollar amt remaining for other books
30 + 14.95 + x ≤ 250
44.95 + x ≤ 250
x ≤ 205.05
x ≤ $205.05 is an inequality that correctly describes this situation.
What is algebraic Expression?Any mathematical statement that includes numbers, variables, and an arithmetic operation between them is known as an expression or algebraic expression. In the phrase 4m + 5, for instance, the terms 4m and 5 are separated from the variable m by the arithmetic sign +.
Let's use x to represent the amount of money Ms. Edwards can spend on other books.
We know that Ms. Edwards can spend at most $250 in total and that she will already spend $30 + $14.95 = $44.95 on the reference books on birds and planets.
Therefore, the amount she has left to spend on other books is:
x = $250 - $44.95
x = $205.05
Ms. Edwards can spend up to $205.05 on other books.
To write this as an inequality, we can use the less than or equal symbol since Ms. Edwards cannot spend more than $205.05:
x ≤ $205.05
Therefore, the inequality that correctly describes this situation is:
x ≤ $205.05

Is this table of values linear?
Answer:
No
Step-by-step explanation:
Linear values will increase by a common difference. For example, a linear function might increase by 6 every time or -4. However, this table does not; each time it increases by a different factor. Since there is no common difference and it does not follow an arithmetic function it is not linear.
Answer:
Step-by-step explanation:
Not linear.
If the inputs were 1, 2, 3, 4 and we wanted a linear function, one such function would be 1, 2, 3, 4 or 10, 20, 30, 40, and so on.
The given table shows that y increases faster and faster as x increases.
From x = 1 to x = 2, y increases from 1 to 2 (an increase of 1).
From x = 2 to x = 3, y increases from 2 to 6 (an increase of 4).
From x = 3 to x = 4, y increases from 6 to 24 (an increase of 18)
No, the table does not represent a linear function.

The total cost of the tent is 409.86
------------------------------------------------------
explanation:
230×0.65=149.50
230+149.50=379.50×.08=30.36
379.50+30.36=409.86
(Hope this helps :) )
============================================================
Explanation:
65% = 65/100 = 0.65
65% of 230 = 0.65*230 = 149.50
When applying markup, the store increases the cost by $149.50 to get the retail price of 230+149.50 = 379.50, which is the price the customer sees. This is the price before tax.
As a shortcut, we can say 1.65*230 = 379.50 because 1.65 = 1 + 0.65 = 100% + 65%. So 1.65 effectively means "increase the value by 65%"
Similarly, the multiplier 1.08 means "increase by 8%". The cost after tax would be 1.08*379.50 = 409.86 which is the answer
----------
As an even quicker shortcut, we can do both increases at once to say:
1.65*1.08*230 = 409.86
The order of multiplication doesn't matter. The two multipliers 1.65 and 1.08 can be combined into 1.65*1.08 = 1.782 which represents a 78.2% increase overall. After the mark up and tax are considered, the jump from $230 to $409.86 is 78.2%
We can apply the percent change formula to confirm this
A = old value = 230
B = new value = 409.86
C = percent change
C = [ (B-A)/A ] * 100%
C = [ (409.86-230)/230 ] * 100%
C = 0.782 * 100%
C = 78.2%
So it might be tempting to say 65% + 8% = 73%, but as you can see above, that calculation is not true.

Answer:
P = 131 degrees
Step-by-step explanation:
We know that the sum of the interior angles of a triangle is 180 degrees
The exterior angles shown form a straight line with the corresponding interior angle
So the two interior angles can be calculated
The sum of two angles on a straight line is 180 degrees
By subtracting the exterior angles from 180, we can get the two interior angles which we can add to the angle at P to give 180
Thus;
P + (180-162) + (180-149) = 180
P + 18 + 31 = 180
P = 180-31-18
P = 131

Stephanie is hosting an art show and she would like to raise at least $800. She plans on
selling VIP tickets to her family and friends for $20 each. She will also sell general admis-

tickets.
Answer: 10, 15
Step-by-step explanation:
Given
Stephanie wants to raise at least $800
she plans on selling VIP tickets for $20 each and general admission for $40 each
suppose there are x and y tickets for VIP and general admission
[tex]\therefore x+y\leq 25\\\\\Rightarrow 20x+40y\geq 800[/tex]
solving above two inequality
Stephanie must sell 10 tickets for VIP and 15 tickets for general admission

What is revenue?Revenue is the money generated from normal business operations, calculated as the average sales price times the number of units sold. It is the top line (or gross income) figure from which costs are subtracted to determine net income. Revenue is also known as sales on the income statement.
Total Revenue = Number of Units Sold X Cost Per Unit
According to the question
a> The company wants to reduce total expenses to $1,300.
Then expenses would i cut is from
Rent expenses as all other expenses are very important but we can try to lower out rent expenses by $1,300.
b>After the decision the impact will be on profit is
It will increase our profit by $1,300 as
Profit = Sales - Expenses
c>if the company increases prices 20%
i.e
If price will be increases then revenue will also increase by 20%
As Total Revenue = Number of Units Sold X Cost Per Unit
Therefore ,
Total Revenue = 356500 * 1.2
= 427800
d> If the cost of supplies (inputs) decreases,
The impact on profit is it will increase
as if cost of supplies decreases that is it will decrease the supplies expenses also which will cost in less expense and higher profit .
e> If the supply of a product goes down,
It will lower the revenue or sales also
as Total Revenue = Number of Units Sold X Cost Per Unit
But if supply of a product goes down and price per unit increase it will maintain the sales or revenue .

An account earns simple interest. Find the annual interest rate. Interest = $60 principle = $500 time = 2 years Please help!!
Answer:
A = $560.00
Step-by-step explanation:
I = A - P = $60.00
Formula:
[tex]A = P(1 + rt)[/tex]
First, converting R percent to r a decimal
r = R/100 = 6%/100 = 0.06 per year.
Solving our equation:
A = 500(1 + (0.06 × 2)) = 560
A = $560.00
The total amount accrued on a principal of $500.00 at a rate of 6% per year for 2 years is $560.00.
