AN Calculators can be purchased for the upcoming end-of-course exam. The revenue function can be modeled as RAN (3) = (25 10x) (300 - 36x) where x is the price of the calculator. MN Calculators can also be purchased for the upcoming exam. The revenue function can be modeled as RuN (x) = (100 20x) (100 - 12x) where x is the price of the calculator. Determine the price of each calculator where the revenue of AN Calculators and MN Calculators are the same.
The revenue functions of the calculator companies is the difference between their cost and profit functions
The price of each calculator when the revenues of AN Calculators and MN Calculators are the same is $2.5
How to determine when the prices are the sameThe revenue functions are given as:
RAN (x) = (25 + 10x) (300 - 36x)
RMN (x) = (100+ 20x) (100 - 12x)
When the prices are the same, we have:
RAN (x) = RMN (x)
So, we have:
[tex](25 + 10x) (300 - 36x) = (100+ 20x) (100 - 12x)[/tex]
Divide through by 20
[tex](5 + 2x) (75 - 9x) = (10+ 2x) (50 - 6x)[/tex]
Using a graphing calculator, we have the following value of x
x = 2.5
Hence, the price of each calculator when the revenues of AN Calculators and MN Calculators are the same is $2.5

3(9)+3(7)
Answer:
48
Step-by-step explanation:
Given the following question:
[tex]3(9)+3(7)[/tex]
To find the answer we need to remember when there is no operation between two numbers and the only thing that is separating them is a paratheses, we know to multiply the two numbers together.
[tex]3(9)+3(7)[/tex]
[tex]3\times9+3\times7[/tex]
[tex]3\times9=27[/tex]
[tex]3\times7=21[/tex]
[tex]27+21[/tex]
[tex]27+21=48[/tex]
[tex]=48[/tex]
Your answer is "48."
Hope this helps.
Answer:
48
Step-by-step explanation:
use PEMDAS
there is no Parenthesis
there is no exponets
there is multiplication
you can rewrite the question like this:
(3x9) + (3x7)
when you do the multiplication you will end up with 27+21. add them and you will get your answer of 48.
or
group the factors. since both of them have 3 in them you add the other quanities which is 9 and 7. you will now have 3(16). multiply it and you will get 48 as well

A group of friends receives a dinner bill of $287.50 at a restaurant. The bill includes a 15% tip for the server.
Part A
How much was the bill before the tip was added?
Enter the correct answer in the box.
Answer:
100%= ?
287.50= 115%
1%= 287.50/115
1%= 2.5
100%= 250
therefore answer is $250
The amount on the dinner bill excluding the tip for the server would be $244.375.
What is percentage?In mathematics, a percentage is a number or ratio expressed as a fraction of 100.
Given is a group of friends who receives a dinner bill of $287.50 at a restaurant. The bill includes a 15% tip for the server.
The initial amount in the bill recieved = $287.5
Percentage tip for server = 15%
Amount recieved by the server = 15% of 287.5 = $43.12
Therefore, the amount before the tip = 287.5 - 43.12 = 244.375
Therefore, the amount on the dinner bill excluding the tip for the server would be $244.375.

Economists study the way society uses its resources. One important resource studied is agriculture. The recent increase in demand for organic produce has created some interesting economic scenarios for both farmers and consumers. Click the article to learn key facts about the economics of organic produce and answer a few questions. Which is a reason that organic farming is more expensive than conventional farming? How many years must a farm be run organically before its produce can be labeled as "organic"? What is a benefit of crop rotation?
Explanation:
Some reasons why organic farming is more expensive than conventional farming is that:
they require greater labor input,the quantity produced is lower which results in a higher cost per unit.it cost more to meet these higher standards.Many agriculturalists believe a farm must be run for at least 3 years organically before its products can be labeled as "organic."
The benefits of crop rotation includes:
it reduces soil erosion,improves soil fertility,it reduces the presence of pests and diseases.
Which is a reason that organic farming is more expensive than conventional farming?

Answer: 67 1/2 cm^3
Solution:
We know that:
Volume of rectangular prism: LBHL = 6; B = 2.5; H = 4.5This means that:
Volume of rectangular prism = 6 x 2.5 x 4.5Step-by step calculations:
Multiply the terms to find the volume:
Volume of rectangular prism = 6 x 2.5 x 4.5=> Volume of rectangular prism = 67.5 cm²The volume of the rectangular prism is 67.5 cm².

Jaylen made strawberry jam and raspberry jam. He made enough strawberry jam to fill 4 5/6 jars. If he made 5 times as much raspberry jam as strawberry jam, how many jars will the raspberry jam fill? Write your answer as a fraction or as a whole or mixed number.
Answer: 24 1/6
Step-by-step explanation:
From the question, we are informed that Jaylen made strawberry jam and raspberry jam and that he made enough strawberry jam to fill 4 5/6 jars.
We are further told that he made 5 times as much raspberry jam as strawberry jam, the number of jars that the raspberry jam will fill will be:
= 5 × 4 5/6
We would change 4 5/6 to improper fraction. This will be 29/6.
= 5 × 29/6
= 145/6
= 24 1/6
