Show answer & explanation
Correct answer: C
Total EVs sold = 2400.
Calculate monthly total EVs using cumulative percentages:
May: 25% of 2400 = 600
June: (41% - 25%) of 2400 = 384
July: (61% - 41%) of 2400 = 480
Calculate monthly Red EVs using cumulative counts:
May: 360
June: 456 - 360 = 96
July: 816 - 456 = 360
Calculate monthly White EVs (Total - Red):
May: 600 - 360 = 240
June: 384 - 96 = 288
July: 480 - 360 = 120
Average White EVs = (240 + 288 + 120) / 3 = 648 / 3 = 216.
