To find out how much more money you need to buy the book, you can set up the following equation:
1. The cost of the book is $12.
2. You currently have $5.
Let \( y \) be the amount of money you currently have. In this case, since you currently have $5, we can substitute \( y \) with $5 in the equation.
The equation to find out how much more money you need (let's call it \( m \)) can be expressed as:
\[
m = 12 - y
\]
Substituting \( y \) with $5, we have:
\[
m = 12 - 5
\]
Calculating this gives:
\[
m = 7
\]
Thus, you need $7 more to buy the book.
If you want to keep it in general terms with \( y \):
\[
\text{More money needed} = 12 - y
\]
