A resistor made of Nichrome wire is used in an application where its resistance cannot change more than 1.00% from its value at 20 °C. Over what temperature range can it be used?

I am confused about Resistivity. #25 to be exact. "For some applications, it is important that the value of a resistance not change with temperature. For example, suppose you made a 4.70-k (ohms) resistor from a carbon resistor to a Nichrome wire-round resistor connected together so the total resistance is the sum of their seperate resistances. What value should each of these resistors have (at 0degreesC) so that the combination is temperature independent?" Like for real? this is so confusing it like gibberish!
