You schedule production of communications chips. After the chips are produced, they go to the QC department, where each chip must pass a 2-hour test. Over the past year, 5.0% of the chips have failed this test. You wish to choose a batch size that will yield as close as possible to 1,000 good chips, on average. Which of the following is the best batch size?

The answer is 270 cars.you can do this by making a proportional relationship. for instance, 200 is the whole we are using, so on a “number line” 200 would be over 100%. now, since he sells 35% more, add 35% to 100% to get 135% on the other side of the “number line” on the bottom half, leaving the top half empty.cross multiply 200 by 135 then divide by 100 to get your answer. i hope this , if it did, , if you don’t mind, giving me brainiest! 200/100% } 200 • 135 /100 ? /135%
