Direct variation problem?? Algebra 2 ….?

From experience, you find that an electric heater radiates five calories per minute when at 300K and 80 calories per minute when at 600K. Bringing the power of the kelvin temperature warms radiation rate varies?? I'm really confused about how to find the "true power" … any help would be greatly appreciated .. verrrrry thank you:)
(P1) / (T1) ^ n = (P2) / (T2) ^ n 5 / 300 ^ n = 80/600 ^ n (600/300) ^ N = 80 / 5 2 ^ n = 16 n = 4
