conversations.value: Bill is signing up for a new streaming service. He got a special introductory deal where the first 6 months were $8 a month, then it went up to the normal price of $12 a month. After 8 months of the normal rate, the service increased its price to $14 a month. How much do 2 years of the service cost him?

conversations.value: There are 12 months in a year, so there are 2 years * 12 months per year = 24 months in 2 years.
  He has 6 months at the special rate, followed by 8 months of the normal rate, so out of 24 months he pays the increased rate for 24 months - 6 months - 8 months = 10 months.
  He pays the special rate of $8 a month for 6 months, or 6 months * $8 per month = $48.
  He pays the normal rate of $12 a month for 8 months, or 8 months * $12 per month = $96.
  He pays the new raised rate of $14 a month for 10 months, or 10 months * $14 per month = $140.
  Over two years, he pays a total of $48 + $96 + $140 = $284.
