Does anyone know how to solve this Physics problem??? Please help!!!?

A certain lightbulb has a tungsten filament with a resistance of 16.0 ohms when cold and 143 ohms when hot. ume that P = IΔV can be used over the large temperature range involved here, and find the temperature of the filament when it is hot. ume an initial temperature of 20°C.
