"Porportional Relationships" means that the rate in which it increases is the same.
For example: 1, 3, 5, 7, 9 is a porportional relationship, because it increases each time by (+2).
Now, look at the first one.
From y to x, y being 2, x being 10, you divided 5 from x to get 2. Next, you divided 6 from 30 to get 5. Because the number dividing is different, it is not proportional

Look at the second one.
From y to x, y being 12, x being 10, you divided 1.2
Now, look at the next one. 30/25 = 1.2
Finally, the last one. 48/40 = 1.2
Because all of them are 1.2, the answer is proportional

You can make an equation for this (x is the number of student tickets)
the number of student tickets is 285
the number of adult tickets is 285+65=350
good luck
Okay, first we have to find the total amount paid:
10050 + 0.2(10050)
12060
Now we find the price paid by each:
12060/2
6030
Each person will pay $60.30
139.25 in = 11 ft 7.25 in
149 3/16 in= 12 ft 5.2 in
