I believe I worked that problem yesterday. Perhaps not for you.
heat needed to move T of ice from -10 to 0
q1 = mass x specific heat ice x delta T
heat needed to melt the ice.
q2 = mass x heat of fusion.
heat needed to move T from 0 to 25.
q3 = mass x specific heat water x delta T.
Total heat required is q1+q2+q3.
Post your work if you get stuck.
