Give the step-by-step reasoning process and then the final answer. Miriam has five times as many albums as Katrina. Katrina has six times the number of albums as Bridget. Bridget has 15 fewer albums than Adele. How many albums do they have together if Adele has 30 albums?
Since Adele has 30 albums, and Bridget has 15 fewer, Bridget has 30 - 15 = 15 albums. Together, Bridget and Adele has 30 + 15 = 45 albums. Katrina has six times the number of albums as Bridget, a total of 15 * 6 = 90 albums. Adele, Bridget, and Katrina have a total of 90 + 45 = 135 albums together. Miriam has five times the number of albums as Katrina, a total of 5 * 90 = 450 albums. Together, Adele, Bridget, Katrina, and Miriam have 135 + 450 = 585 albums.
The final answer: 585.
