Answer:
D. 67
Step-by-step explanation:
To help me see the region we needed to look at, I wrote the inequalities out.
Let x be number of pre-sale tickets and y be the number of at-the-door tickets as your graph suggests.
So one of the inequalities about number of where the other one is about cost.
You are given x+y is no more than 400 or x+y<=400 (the top line graphed in your picture is x+y=400).
You are given 10x+25y is at least 5000 or 10x+25y>=5000 (the bottom line graphed in your picture).
I solved both of these for y.
Direct proportionality is the type of proportionality where an increase in one quantity or variable causes a corresponding increase in another quantity.
Therefore; y varies directly as x
Hence; y α x
y =k x where k is a constant
if y= 28 and x = 7 , then k = 28/4 =4
hence, y = 4 k
when x = 4, then y= 16
