Hey there!
To start, first set up a proportion where x is the cost to make 27 copies:
27/x=150/4.50
Now, solve for x by cross multiplying which should look like this:
27*4.50=x*150
Now simplify and solve for x:
121.5=150x
x=0.81
Therefore, it costs $0.81 to make 27 copies.
Hope this helps!

Answer: 2/3</h3>
Explanation:
The theoretical probability of landing on a multiple of three is 1/3
So the theoretical probability of not landing on a multiple of three is 1-(1/3) = 3/3-1/3 = (3-1)/3 = 2/3
We can think of 1/3 to mean "1 out of 3 times", while 2/3 means "2 out of 3 times".
