hannah and mallory are selling boxes of cookies for a school fundraiser. each box costs the same amount. hannah sells 14 boxes.

aleksley [76]

The cost per box of cookies is $3.75

The total amount Hannah raised from the sales of cookies is $52.50

The total amount Mallory raised from the sales of cookies and donations is $88.50

In order to determine the cost per box of cookies, take the following steps:

The first step is to determine the total sum of the boxes sold by Hannah and Mallory

Sum of the boxes sold = 14 + 22 = 36 boxes

36 boxes were sold by Hannah and Mallory

The second step is to determine the total cost of the 36 boxes sold.

Total cost of 36 boxes = total amount raised - donation

$141 - $6 = $135

The third step is to determine the total cost of each box

cost of one box = total cost of 36 boxes / total number of boxes

135 / 36 = $3.75

The total amount Hannah raised = cost per box x number of boxes she sold

14 x $3.75 = $52.50

The total amount Mallory raised = amount raised from the sale of cookies + donation

amount raised from sales = cost per box x number of boxes she sold

22 x $3.75 = $82.50

Total amount = $82.50 + $6 = $88.50

Many us employess received a 3% raise in 2012 suppose an employee made 47,000 in 2011 and received a 3% raise. What did she make

WITCHER [35]

First lets get 3% into decimal form.

3% is 3/100 = 0.03

Now multiply 0.03 by 47000 to get how much extra money she was going to get.

47000 * 0.03 = 1410

Now we just add
47000 + 1410 = 48410 is what she was going to make in 2012

Another way to do this is

(47000)(1+0.03) = 48410

you would use (1+0.03) which tells you she increased in pay.

You have a stack of 99 different books, and you are putting them all on your shelf. How many different ways are there for you to

Tanzania [10]

Answer:

$9.332622\times 10^{155}$

Step-by-step explanation:

Before getting the final result, let's analyse the same situation but with less books for having a better perspective. For example, just 3 books, named: A, B and C

3 books mean 3 spaces

At the beginning, the first space has 3 ways to be occupied: they are book A, B or C.

If the first place is already occupied for any of them, then, the second place could be occupied just by the two others. If the second place is occupied by any of those two, finally, the third space just could be occupied by one.

Imagine that first space is occupied by book A. The ways to arrange the other books would be:

Book A ----- Book B ----- Book C
Book A ----- Book C ----- Book D

As you see, there are two ways to arrange them positioning the book A at the beginning. The same would happen with book B and book C at the beginning. It means there are 3 options at the beginning and then just 2.

If we multiply those values we get the total ways. It means 6 ways.

Real Problem

Now, for the 99 different books the analysis would be the same:

At the beginning would be 99 books to put in the first space, then in the second space would be 98, then 97, then 96, and so on, until 1.

But it is not a problem because there is a way to write it. It is called factorial.

$99! = 99\times 98\times 97\times 96\times ...\times 3\times 2\times 1$

If we make all this multiplication we get $9.332622\times 10^{155}$ ways to order the 99 books.
