To solve for \( x \) in the inequality \( 4x + 36.00 \leq 52.00 \), follow these steps:
- Subtract 36.00 from both sides to isolate the term with \( x \):
\[ 4x \leq 52.00 - 36.00 \]
\[ 4x \leq 16.00 \]
- Now, divide both sides by 4 to solve for \( x \):
\[ x \leq \frac{16.00}{4} \]
\[ x \leq 4 \]
Thus, Frank can buy up to 4 treats (where \( x \) is the number of treats).
