3. high-school physic quiz question on impulse

how do I know when finding final momentum, I am using 2.34-1.026 because finding final momentum, I thought it is Mf(Vf)? 2.34 is change in momentum. 1.026 is Initial impulse.

I get it now. Its telling me to rewrite it in another way that is similar to the equation as certain letters equal a certain equation.  But they are all the same. Thanks
