Arranging of books is an illustration of permutation and combination
There are 24 different possible arrangements she can make
<h3>How to calculate the number of arrangement</h3>
The number of books is given as:
n = 4
Take the factorial of both sides
n! = 4!
Evaluate
n! = 4 * 3 * 2 * 1
n! = 24
Hence, there are 24 different possible arrangements she can make

Answer:
Step-by-step explanation:
-5x - 8y = -3
5x + 9y = 3
y = 0
5x + 0 = 3
5x = 3
x = 3/5
(3/5, 0)
Answer:
24
Step-by-step explanation:
First find the area of the metal plate: 32*12=384
Find the are of each small square to see how much space it takes: 4*4=16
Divide the two to see how many can fit: 24

<h3>The projected amount the average American spent on health care in 2014 is $ 10075.91</h3>
<em><u>Solution:</u></em>
Given that,
The average American spent $8,508 on health care in 2011
The cost of health care is projected to rise about 5.8% per year for the years 2012-2022
<em><u>The increasing function is given as:</u></em>

Where,
y is future value
a is initial value
r is growth rate in decimal
t is number of years
From given,
a = 8508

t = 2011 to 2014 = 3 years
<em><u>Substituting the values, we get,</u></em>

Thus the projected amount the average American spent on health care in 2014 is $ 10075.91
