conversations.value: I'm stuck on this math problem: Southton buries their time capsule 15 feet underground. Northton buries their time capsule 12 feet higher than 4 times the depth of the Southton time capsule. How deep is Northton's time capsule buried?
  Can you help?

conversations.value: First multiply the depth of Southton's capsule by 4: 15 feet * 4 = 60 feet
  Then subtract 12 feet to find the depth of Northton's time capsule: 60 feet - 12 feet = 48 feet
