The problem given can be solved using a system of linear equations. We can define the following variables:

- Let $ x $ represent the price of one composition book.
- Let $ y $ represent the price of one pen.

From the information provided in the image:

1. The first scenario says 9 composition books and 7 pens cost $46.80:
   \[
   9x + 7y = 46.80
   \]

2. The second scenario says 2 composition books and 17 pens cost $38.20:
   \[
   2x + 17y = 38.20
   \]

We now have a system of equations:
\[
\begin{align*}
9x + 7y &= 46.80 \\
2x + 17y &= 38.20
\end{align*}
\]

I will solve this system of equations to find $ x $ and $ y $.The price of one composition book is $3.80, and the price of one pen is $1.80.

2. If the price of composition books increases by $0.50, what would the new price be?
3. How many pens can you buy for $20 at the current price?
4. What would be the cost of 3 composition books and 8 pens?
5. If you buy 4 composition books and 4 pens, how much will you spend?
