To solve this problem, you will need to set up a proportion.
Let x = the unknown cost of the books.
![\frac{1}{1.95} = \frac{6}{x}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B1.95%7D%20%3D%20%5Cfrac%7B6%7D%7Bx%7D)
Assuming the cost of books stays constant, you can crossmultiply and solve for x.
x = 1.95(6)
x = 11.70
Six books will cost $11.70 if 1 book cost $1.95.

Step-by-step explanation:
![Area = \: \frac{bh}{2} \\ : b = 16.9 \: h = 10.4 \\](https://tex.z-dn.net/?f=Area%20%3D%20%5C%3A%20%20%5Cfrac%7Bbh%7D%7B2%7D%20%20%20%5C%5C%20%3A%20b%20%3D%2016.9%20%5C%3A%20h%20%3D%2010.4%20%5C%5C%20)
![Area = \frac{16.9 \times 10.4}{2} = \frac{175.76}{2} = 87.88 {ft}^{2}](https://tex.z-dn.net/?f=Area%20%3D%20%5Cfrac%7B16.9%20%5Ctimes%2010.4%7D%7B2%7D%20%20%3D%20%20%5Cfrac%7B175.76%7D%7B2%7D%20%20%3D%2087.88%20%7Bft%7D%5E%7B2%7D%20)
Base = 16.9
height = 10.4
Area = ½b×h
A = ½(16.9×10.4)
A = ½(175.76)
Area = 175.76/2
A = 87.88ft²
Answer:
1.

3.
.
4.
.
5.
.
Step-by-step explanation:
1. The product of the third power of a and the fourth power of b =
.
The 'third power of a' means 'a to the power 3' and 'fourth power of b' means 'b to the power 4'.
2. Six less than three times the square of Y means
.
Here, 'three times the square of Y' means 'product of 3 and Y to the power 2', and 'six less than' means 'subtract 6 from the expression'.
3. The sum of a and b increase by the quotient of b and a means
.
Here, 'quotient of b and a' means 'b divided by a'.
4. Four times the sum of r and a increased by twice the different r and s means
.
Here, 'increased by' means 'addition' and 'different r and s' means 'r minus s'.
5. Triple the difference of 55 and cube of w means
.
Here, triple means 3 times. (Answer)
In this case if x<100 George will be losing money. So he will only earn a profit when he sells more than 100 DVDs. Essentially (x-100) represents his break-even point.
