q for ice at -20 to ice at 0.
q = mass x specific heat ice x delta T (dT = 20).
q to melt the ice is
q = mass ice x heat fusion.
q to heat from zero to 95.
q = mass H2O x specific heat H2O x dT and dT = 95.
Then sum the q values.
Calculate the amount of energy in calories that is needed to melt 45g of ice at -20°C and then increase the temperature to 95°C
