To express the number of blue markers in the drawer in terms of the variable \( r \) (which represents the number of red markers), we can use the phrase from the problem: "The number of blue markers in a drawer is 4 more than twice the number of red markers."
We can set up the expression as follows:
- Twice the number of red markers: This is represented as \( 2r \).
- 4 more than that: To gain the total for blue markers, we add 4 to \( 2r \).
Thus, the expression for the number of blue markers \( b \) in terms of \( r \) is:
\[ b = 2r + 4 \]
Now we have an expression for the number of blue markers. Would you like to continue and find the total number of markers in the drawer?
