Answer:

25

Step-by-step explanation:

We can have a set of equations for this. Let x be the number of 1 pound coins and y be the number of 2 pound coins.

We can set an equation like this:

Since she has twice as many 1 pound than 2 pound coins, we can set this equation:

x=2y

Since the worth of the coins add up to 100:

(1 pound)*x+(2 pounds)*y=100pounds

x+2y=100

We can substitute x=2y

2y+2y=100

y=25

Therefore we have 25 2 pound coins
