conversations.value: I'm completely lost with this math problem: Jeremy bought a computer for $3000, and some accessories for 10% of the price of the computer. How much money has Jeremy if, before the purchase, he had two times more money, than the cost of the computer itself?
  Can you give me a hand?

conversations.value: At the start, Jeremy had two times more money than the price of the computer, which means he had 2 * 3000 = $6000.
  The cost of the accessories stands at 3000 * 1/10 = $300.
  This leaves Jeremy with 6000 - 3000 - 300 = $2700.
