conversations.value: Explain how to solve this math problem: Miley bought two cellphones for her parents. Each cellphone costs $800 but, since she is buying two units, she will receive a 5% discount for the total cost. How much did Miley pay?

conversations.value: Two cellphones cost $800 x 2 = $1600.
  The 5% discount amounts to $1600 x 5/100 = $80.
  So Miley paid $1600 - $80 = $1520.
