Solve x3 = 125 over 27. 25 over 9 ą25 over 9 5 over 3 ą5 over 3

15.36 per mile

but forgot to round

i am pretty sure

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.
