Let the maximum number of pages Jennifer can have be = x
Amount Jennifer has (P) = $62.10
Given equation is :
P = ![(20+0.5x)+0.15(20+0.5x)](https://tex.z-dn.net/?f=%2820%2B0.5x%29%2B0.15%2820%2B0.5x%29)
Price is given = 62.10 , so equation is :
![62.10=20+0.5x+3+0.075x](https://tex.z-dn.net/?f=62.10%3D20%2B0.5x%2B3%2B0.075x)
![62.10=23+0.575x](https://tex.z-dn.net/?f=62.10%3D23%2B0.575x)
![0.575x=39.10](https://tex.z-dn.net/?f=0.575x%3D39.10)
![x=68](https://tex.z-dn.net/?f=x%3D68)
Hence, Jennifer can have a maximum of 68 pages in her book.

Answer: no
Step-by-step explanation:
no. one is the fraction 1 / 3 and the other is the fraction 3 / 1
Let's define the following variables first.
A = number of tickets sold for adults
C = number of tickets sold for children
From the question, we can say that or form the following equations:
1. A + C = 790 tickets
2. $7A + $4C = $4, 390
The first equation can also be written as A = 790 - C. We can use this equation and replace "A" in the second equation.
![7(790-C)+4c=4,390](https://tex.z-dn.net/?f=7%28790-C%29%2B4c%3D4%2C390)
From that, we can solve "C" by solving the equation formed above.
![\begin{gathered} \text{Distribute 7 to the terms inside the parenthesis.} \\ 7(790)-7(C)+4C=4,390 \\ 5,530-7C+4C=4,390 \\ \text{Subtract 5,530 on both sides of the equation.} \\ -7C+4C=-1140 \\ -3C=-1140 \\ \text{Divide -3 on both sides.} \\ C=380 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%5Ctext%7BDistribute%207%20to%20the%20terms%20inside%20the%20parenthesis.%7D%20%5C%5C%207%28790%29-7%28C%29%2B4C%3D4%2C390%20%5C%5C%205%2C530-7C%2B4C%3D4%2C390%20%5C%5C%20%5Ctext%7BSubtract%205%2C530%20on%20both%20sides%20of%20the%20equation.%7D%20%5C%5C%20-7C%2B4C%3D-1140%20%5C%5C%20-3C%3D-1140%20%5C%5C%20%5Ctext%7BDivide%20-3%20on%20both%20sides.%7D%20%5C%5C%20C%3D380%20%5Cend%7Bgathered%7D)
Therefore, 380 tickets for children were sold.
Since there are 790 tickets in total that are sold and 380 tickets for children were sold, we can say that 410 tickets for adult was sold.
