The answer is 2^12 = 4096.

Look at a tree diagram. With one spin there are two possible outcomes (branches). Every time you spin, each of the branches split into two more branches.
With 12 spins, first there are 2 branches, then 2*2, then 2*2*2, ... In the end it's 2^12

Answer:

The student ticket is 200 and the adults is 550

Step-by-step explanation:

So the set up is :

750 = x + y

5300 = 8x + 4.5 y

x will be adults and y will be students

Assuming you don't have calculator then you want to be able to eliminate either x or y from this system. The easiest is X cause its a whole number.

So multiply all the numbers from the first equation by 8 which gives

6000 = 8x + 8 y

5300 = 8x + 4.5 y

Then subtract the numbers (6000-5300 and 8x-8x and 8y-4.5y)

which gives :

700 = 3.5y

Solve for y = 200

and plug 200 back into any equation to solve for X

750 = x + 200

x = 550
