This is a perfect calculator question. Just add the Morning Shift and the Afternoon Shift for each day and see which total is the greatest. Write each total down next to the day on the chart, so you don't have to keep track of it all in your head. Monday is 200+375=575, Tuesday is 245+330=575, Wednesday is 255+340=595, Thursday is 250+315=565, and Friday is 225+360=585. According to these calculations, Wednesday and Friday have the two greatest totals, so the greatest number of computers is produced on those two days together, making (C) the right answer.
