How much heat is required to raise the temperature of a mole of oxygen from 298 to 3000 K at constant pressure?

The book gives the following values for Cp (specific heat at constant pressure): 29.376 J/(K*mol) at 298 K and 39.884 J/(K*mol) at 3000 K.

The correct answer is 98.098 kJ/mol. But I don't know how to get it.
