conversations.value: Lisa bought a new iPhone for $1000. She bought a phone contract that costs $200/month, a case that costs 20% of the cost of the phone, and headphones that cost half as much as the case. How much will Lisa spend on her phone in the first year?

conversations.value: First find the cost of the case: $1000 * 20% = $200
  Then find the cost of the headphones: $200 / 2 = $100
  Then find how much the phone contract will cost over a year: $200/month * 12 months/year = $2400
  Finally, add the cost of the phone, accessories, and plan over the first year to find the total: $2400 + $100 + $200 + $1000 = $3700
