In general the binomial expansion is
So in our case, because we want ascending powers of x we'll write,
We need to calculate the binomial coefficients:
First, you would create an equation for this problem.
= 
Next, you would cross multiply.
15x = 1,800
Now, you would isolate the x. To do this, you would divide both sides by 15.
x = 120
It is a 120% increase.
I hope this helps!
