conversations.value: Daniel practices for a total of 15 x 5 = 75 minutes during the school week.
  He practices 15 x 2 = 30 minutes each day on the weekend.
  So, he practices a total of 30 x 2 = 60 minutes on the weekend.
  Thus, Daniel practices for a total of 75 + 60 = 135 minutes during a whole week.
