Carlos used the following units of electricity for twelve months: 504, 519, 576, 321, 256, 101, 76, 75, 127, 289, 367, and 511. his average unit consumption is

The average units will be calculated by adding the units for the 12 months and divide by 12:
504+519+576+321+256+101+76+74+127+289+367+511= 3722 units
then divide the sum of the units by the number of months (12)
3722/12=310.17units
Carlos average unit consumption is 310.17
