To find the number of nickels Jason has, we need to translate the information given into an equation and solve for the unknown.

Let's assign variables to represent the unknowns:
Let's say the number of quarters is 'q'
And the number of nickels is 'n'

We know that Jason has twice as many nickels as he has quarters, so n = 2q.

We are also told that Jason has a total of 12 coins, so the number of quarters plus the number of nickels equals 12: q + n = 12.

Now we can substitute the value of n from the first equation into the second equation:

q + 2q = 12
3q = 12
q = 12 / 3
q = 4

So, Jason has 4 quarters.

Now, we can substitute the value of q back into the first equation to find the number of nickels:

n = 2q
n = 2*4
n = 8

Therefore, Jason has 8 nickels.
