You are assembling cars, and your job is to put the wheels on the vehicles. you have 3520 wheels, 14040 nuts (4 nuts needed per wheel) and 1000 car bodies at the start of the day (you have time to do more than 1000, and there will be no deliveries of additional parts during the day). how many possible cars can roll off the assembly line? what is the limiting reagent in this case? if you only get to put the wheels on 850 cars that day, what is your productivity?
