conversations.value: Provide a step by step solution for the following math problem: Shiela bought five cell phones for $150 each for a 3-month installment. A 2% interest will be charged for each unit. How much will Shiela pay each month for 3 months?
conversations.from: assistant
conversations.value: A $150 x 2/100 = $3 interest will be charged for each unit.
  So, each cell phone costs $150 + $3 = $153.
  The total amount to be paid for 5 cell phones is $153 x 5 = $765.
  Thus, Shiela will pay $765/3 = $255 each month.
