The local planetarium is selling tickets for the new laser light show at the price of 2 tickets for $5.00 which graph shows the relationship between the number of tickets bought and the total cost?

I need the different options of graphs then i will answer it.

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.

my apex says that it is false
