Answer:
$35 per ticket
Step-by-step explanation:
1120 divided by 32 is 35, I used a calculator. If you divide the cost by the quantity you will get the cost for one quantity
So, we know that:

We also know that
. We will use that fact to find
in terms of
and
.

Therefore:

This can be solved by Newton's binomial formula
Tk+1 = (n k) a∧(n-k) b∧k k+1=7 => k=6, n=11 , a=-3x and b=-2y
T7= (11 6) (-3x)∧(11-6) (-2y)∧6 = (11*10*9*8*7)/(1*2*3*4*5) (-3x)∧5 (-2y)∧6
T7= 462 (-3x)∧5 (-2y)∧6
The correct answer is A.
Good luck!!!
