To find the volume of liquid in Jamal's flask, which has 30% more than Carl's flask (which has \( x \) milliliters), we can express this as follows:
- 30% of \( x \) is \( 0.3x \).
- Therefore, the total volume in Jamal's flask would be: \[ x + 0.3x = 1.3x \]
Thus, both expressions \( x + 0.3x \) and \( 1.3x \) represent the number of milliliters of liquid in Jamal's flask.
So, the correct answer is Both the answers.
