Apark manager claims that the profit p for a concession stand depends on the number of
visitors v and that the number of visitors
depends on the day's temperature t (in
degrees fahrenheit). the following equations
represent the manager's claims. p=4.25V-300
v=50(t-45)

i need the options

step-by-step explanation:

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.
