You also notice that, on average, you only feel confident enough to respond to 12 of the 20 questions on a typical episode.
so, if you respond to only 12 questions when you're on the show, which two equations describe your winning scenario?
select all the correct answers.
100x - 200y = 600
x + y = 600
100x - 200y = 12
x - y = 600
x + y = 12

13cm

step-by-step explanation:

(apex)

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.
