conversations.value: Janice has been working part-time at a convenience store 5 days a week. She can earn $30 per day and can earn $15 more when she works a 2 hour overtime shift. If she works three overtime shifts this week, how much will she earn this week?
  Give me a clear explanation.

conversations.value: Janice can earn $30 x 5 = $150 per week.
  She will earn $15 x 3 = $45 more if she works three overtime shifts.
  Therefore, Janice will earn $150 + $45 = $195 this week.
