Reasoning and answer: First, we need to determine how many cell phones each machine makes per minute. We do this by performing 10 / 2 = 5 cell phones each minute per machine. Next, we determine how many machines are needed in total by dividing the desired outcome of 50 by the rate of production of an individual machine, finding 50 / 5 = 10 machines needed.
The answer: 10
