May someone answer this word problem: From the Period-Luminosity relation for Cepheid variable stars, you deduce that the luminosity of a particular star is 50 times the luminosity of an RR Lyrae star. You measure the apparent brightness of the RR Lyrae variable to be 1% of the brightness of the Cepheid variable. If the RR Lyrae variable is at a distance of 1,000 pc, how far away is the Cepheid variable?
