What are the total sales of cars of the four manufacturers under consideration in the city in the entire period of 6 years (from 2015 to 2020)?
Answer & explanation
Correct answer: option 2
Total sale of cars of the four manufacturers over all 6 years = ( 44 + 48 + 47 + 50 + 52 + 51 ) + ( 40 + 41 + 41 + 51 + 42 + 43 ) + ( 36 + 38 + 40 + 42 + 44 + 50 ) + ( 48 + 44 + 44 + 42 + 42 + 43 )
= 1053 ( in thousands )
= 1053000
