conversations.value: I'm completely lost with this math problem: As soon as you enter the taxi, you pay a ride fee of $2. Michelle rode a taxi from her office to her home, which constitutes 4 miles. If the taxi charge per mile is $2.5, how much did pay Michelle pay in total for her ride?
  Can you give me a hand?

conversations.value: The taxi charge for a distance of 4 miles is 4 x $2.5 = $10.
  The total amount that Michelle paid for the ride was $2 + $10 = $12.
