If they manage to sell
tickets, they will earn
dollars. We want this number to be at least 1000, so the inequality would be

In order to solve this for t, you only need to divide both sides by 15:

So, they need to sell at least 67 tickets to have an income of
dollars
Container A:
y=-6x+800
800 is y intercept( it already have 800 before leaking)
leaking means that its went down so it had to be negative -6x)
container B:
y=-10x+1000
same thing with a container B
-6x+800=-10x+1000 = 800-6x=1000-10x
Convert 12 pounds to ounces which is 192 ounces.
Divide the price by the ounces. That would get $0.09765625 rounded to $0.10 per ounce.
