Answer:
x= -136
Step-by-step explanation:
A bookstore is deciding what price it should charge for a certain book. After research, the store finds that if the book's price is p dollars (where p <= 40), then the number of books sold per month is 120-3p. What price should the store charge to maximize its revenue?
The store charge that has to be charged should be 20$
How to solve for the chargeFirst we have to solve for revenue
Revenue = Price x quantity
= p * 120-3p
= 120p - 3p²
The maximum revenue is at the point where p = - b/2a
Hence we have
-120/2 *-3
= -120/-6
= $20
Hence the amount that has to be charged by the store should be $20

Describe the probability of rolling a number greater than 5 on a standard number cube.
Answer:
1:6
Step-by-step explanation:
there are 6 numbers on a standard dice. 1, 2, 3, 4, 5 are all less than or equal to 5. So, the only numver greater than 5 is 6. the probability 1/6
The probability of rolling a number greater than 5 on a standard number cube will be 1/6.
What is probability?Its basic premise is that something will almost certainly happen. The percentage of favorable events to the total number of occurrences.
The probability of rolling a number greater than 5 on a standard number cube will be
The total number of the event will be
Total event = 6 {1, 2, 3, 4, 5, 6}
The favorable event will be
Favorable event = 1 {6}
Then the probability will be
P = 1/6

If you were babysitting, would you rather
Charge $5 for the first hour and $8 for each additional hour?
Or
Charge $15 for the first hour and $6 for each additional hour?
Explain your reasoning.
Answer:
Depends on how long. $8 every additional hour would be the better deal unless you go at or over 6 hours. If you're planning on babysitting for 5 hours or less, go with option A. If 6 hours or more, go with option B.
Answer:
Depends on how long and the child
Step-by-step explanation:
If you're babysitting for like 3 1/2 hours the first option if you're babysitting for longer than the second option and also if the kid is bugging you a lot :/ then the second one because you're working harder and the harder you work the more money you should earn :D
1. Create a scenario that leads to an inequality of the form ax + b > c. You can use any of the inequality symbols (>, ≥, <, ≤) in your inequality. For this step, just write the word problem.
2. Write the inequality and show all work to solve the inequality.
3. Graph the solution to your inequality on a number line.
4. Explain what your solution means in the context of the problem
Answer:
1) Ola taxi charges a $8 flat rate in addition to $2 per mile. Paul has no more than $10 to spend on a ride.
2) Let x be the number of miles.
Then, we have inequality: [tex]8x+2\leq 10[/tex]
Solve the inequality: [tex]8x+2\leq 10[/tex]
Subtract 2 from both the sides: [tex]8x+2-2\leq 10-2[/tex]
Simplify: [tex]8x\geq 8[/tex]
Divide by 8 both sides we get: [tex]x\leq 1[/tex]
as shown in figure 1.
3) From the context of the problem : we can say that Paul can travel 1 miles or less before reaching his limit of $10.

In Mrs. Wilson's math class, the ratio of girls to total students is 5 to 8. If there are 24 total students, how many boys are in the class? (help please! i also need work for understanding this problem, thank you!)
Answer:
9 boys are in the class
Step-by-step explanation:
5 to 8
5 x 3 = 15 girls
24 - 15 = 9 boys
9 boys in the class
There are 9 boys in the class.
What is Ratio?
A ratio indicates how many times one number contain in another number.
Given that;
In Mrs. Wilson's math class,
The ratio of girls to total students is 5 to 8.
Total student in the class = 24
Now, Let number of girls = 5x
And, Total number of student = 8x
Since, Total student in the class = 24
Hence,
8x = 24
x = 24/8
x = 3
Thus, Number of girls = 5x = 5 × 3 = 15
So, Number of boys = total student - number of girls
= 24 - 15
= 9
Thus, There are 9 boys in the class.
