A geologist takes samples of two rocks from a mountainside. The gray rock has a volume 25% higher than that of the brown rock. However, the brown rock’s density is 80% greater than the gray rock’s density. If the gray rock has a mass of 5 grams, what is the mass of the brown rock, in grams? (Density is defined as mass divided by volume.)
