How much would you raise the temperature of a cooper wire (originally at 20 degrees Celsius) to increase its resistance by 17%?

I need a full detailed explanation on how to solve this problem.

R=Ro[1+α(T-To)], where R is the resistance and Ro is the initial resistance. α is the temperature coefficient (α=.004 for copper), T is the temperature and To is the initial temperature, 20 celcius in this case.

R/Ro=1.17 since it increases by 17% so



T=62.5 degrees Celsius
