Calculators are sold to students for $20 each. 300 students are willing to buy them for that price. For each five dollars increase in price, there are 30 fewer students that are willing to buy the calculator. a. what selling price will produce the maximum revenue?
b. what will the maximum revenue be?
Answers
Answer:
a) 40$ b) 7600
Step-by-step explanation:
In my opinion, the best way to go about this is to simply start by doing 20×300, 25×270, 30×240, etc. Once I reached 40, I realized that my revenue was going down after it, so I saw that a 40 dollar starting price would being in more money. 40×190 - (the amount of students who will buy at that price) equals 7600, which will be your maximum revenue. I hope i could help, good luck.

Therefore, the factors of 15 are 1, 3, 5, and 15. The number 15 has more than two components, making it a composite number.
A number that equally divides into a number is referred to as a factor, to give a more thorough explanation.
A factor of 15, for instance, is 3 since 15 / 3 equals 5. A number with precisely two elements, 1 and itself, is said to be a prime number. For instance, the only integers that divide evenly into 2 are 1 and 2, making 2 a prime number.
A number with more than two elements is said to be composite. For instance, 15 is a composite number since 1, 3, and 15 are all divided evenly into 15.
Therefore, 1, 3, 5, and 15 are the factors of 15. 15 has more than two components, making it a composite number.

Answers
10n-100=6n
We move all terms to the left:
10n-100-(6n)=0
We add all the numbers together, and all the variables
4n-100=0
We move all terms containing n to the left, all other terms to the right
4n=100
n=100/4
n=25
I think “n” is 6

The required factor of the given expression x² -8x + 16 is (x - 4)².
What is factor?
In mathematics, a factor is a number or algebraic expression that divides another number or expression evenly without leaving a remainder.
To factor the expression x² - 8x + 16, we can use the following steps,
- Step 1: Identify the first and last terms of the expression, which are x² and 16, respectively.
- Step 2: Find two numbers that multiply by 16 and add up to -8. In this case, these numbers are -4 and -4, since (-4) x (-4) = 16 and (-4) + (-4) = -8.
- Step 3: Rewrite the middle term of the expression (-8x) as the sum of the two numbers found in step 2, i.e., -4x - 4x.
- Step 4: Factor by grouping, by grouping the first two terms (x² - 4x) and the last two terms (-4x + 16) separately, and factoring out the common factor in each group
= x² - 4x - 4x + 16
= x(x - 4) - 4(x - 4)
= (x - 4)(x - 4)
Step 5: Simplify the result by writing (x - 4)(x - 4) as (x - 4)².
Therefore, the factored form of x² - 8x + 16 is (x - 4)².
