What is the average number of White EVs sold in May, June and July together?
White each month is the monthly total minus the monthly Red. May total is 600 and Red is 360, so White is 240. June total is 384 and Red is 96, so White is 288. July total is 61 percent of 2400 minus 984, that is 1464 minus 984 which is 480, and Red is 816 minus 456 which is 360, so White is 120. The average of 240, 288 and 120 is 648 divided by 3, which gives 216.
