To set up the inequality based on the given problem, we need to interpret the phrase "Fifteen less than four times a number".
Let's denote the number as \( x \). "Four times a number" would be represented as \( 4x \). "Fifteen less than four times a number" means we subtract 15 from \( 4x \), which gives us \( 4x - 15 \).
The problem states that this quantity is more than 49, which can be expressed as:
\[ 4x - 15 > 49 \]
So the completed inequality is:
\[ 4x - 15 > 49 \]
