Answer:
Jorge needed to have over 13 (thirteen) 9 volt batteries to create 120 volts.
Explanation:
Rather than saying he just needs 13 1/3 (one-quarter) 9 volt batteries, Jorge would have correctly concluded he needed over over 13 number of 9 volts battery to create 120 volts.
This is the case because in a series connection, two or more batteries are connected in a way that the same current would flow through each battery through their terminal. If he had taken note of the fact that each battery has an internal resistance, which may reduce the flow of current through the batteries Jorge would know that the 13 number of 9 volts batteries would not give exactly 120 volts because of the internal resistance of the battery circuit.
