help Lorenzo is using the dot plots to compare two sets of data. Both plots use the same number line. Which choice most likely describes the data sets Lorenzo is comparing?

answer is because 4×10=40

and 98×4= is 392

40,392

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.
