The group started with one battery in their circuit. each time they increased the current, they were adding a single additional battery. If their circuit had a resistance of 150 Ohms, what was the voltage of a single battery? Show your work.

As far as I know, the question can't be answered because you haven't provided how much current each battery has or how much the current is increasing by for each additional battery.
The formula for voltage in this problem is Voltage = Current x Resistance. If I knew how many amperes of current were in the circuit, then I would know the total voltage. From there you would divide that total number by the number of batteries in order to get the voltage of a single battery.
For example, let's say that 4 batteries gave a current of .25 amps.
V = .25 x 150
V = 37.5 volts.
There were four batteries connected up, so divide 37.5 volts by 4. You get 9.375 volts per battery. Without knowing the current though, my numbers are hypothetical.
