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?

Answers

The store charge that has to be charged should be 20$

How to solve for the charge

First 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

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!)

Answers

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.

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.

Answers

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

What is the equation for "p", the number of pounds it would take for the cost of the two shipping companies to be the same?

Answers

Answer:

answer is on the bottom

Step-by-step explanation:

Company 1: y=0.45x+10

company 2: y=0.30x+14

To find when they are both the same, put an equal sign and solve:

0.45x+10=0.30x+14

         -10             -10

0.45x=0.30x+4

-0.30x  -0.30x

0.15x=4

divide by 0.15 on both sides and you got ur answer :) happy to  help
