"What percentage of heat is used to raise the temperature of the water? (See Table 8.2)" the solution manual has you divid 1.30*10^5 by our answer from part a where does this number come from?

1.30*105 J is the amount of energy it takes to raise the temperature of water which is calculated by (400.0 g)(4.18)(100.0-22.0). 1.45*105 is the total amount of energy it takes to raise the temperature of both the water and the kettle itself.
