conversations.value: Mark was caught speeding and the judge wants to make an example out of him. The base fine for speeding is $50 but additional penalties apply in this case.  The fine is increased by $2 for every mile per hour Mark was going over the speed limit. He was going 75 miles per hour in a 30 mile per hour zone. The fine is also doubled because he was in a school zone. Finally, the judge makes Mark pay $300 in court costs and he also has to pay his lawyer $80/hour for three hours of work. How much does Mark owe for this speeding ticket?
  Give me a detailed solution.

conversations.value: First figure out how many miles over the speed limit Mark was going: 75 mph - 30 mph = 45 mph
  Now figure out how much the per-mile fine is: $2/mph * 45 mph = $90
  Now add that amount to the base fine: $90 + $50 = $140
  Now double that amount for being in a school zone: $140 * 2 = $280
  Now figure out how much Mark owes his lawyer: $80/hour * 3 hours = $240
  Now add the court costs, lawyer fees and fine: $240 + $300 + $280 = $820
