Evan says that the value of the numerical expression 0.2+ 12 ÷ (1.5×4) is 32.04 . do you agree ?

NO! The correct answer is 2.03 (where 3 is repeating)

Step-by-step explanation:

0.2 + 12 / (1.5*4) does not equal 32.04

Parenthesis first! 1.5 times 4 equals 6.

0.2 + 12 = 12.2

12.2/6

12.2/6= 2.0333... but it should be rounded to 2, because

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.
