conversations.value: Can you guide me through solving this problem: Janet pays $40/hour for 3 hours per week of clarinet lessons and $28/hour for 5 hours a week of piano lessons. How much more does she spend on piano lessons than clarinet lessons in a year?
conversations.from: assistant
conversations.value: First find the total Janet spends on clarinet lessons per week: $40/hour * 3 hours/week = $120/week
  Then find the total Janet spends on piano lessons per week: $28/hour * 5 hours/week = $140/week
  Then subtract her weekly clarinet spending from her weekly piano spending to find the weekly difference: $140/week - $120/week = $20/week
  Then multiply the weekly difference by the number of weeks in a year to find the annual difference: $20/week * 52 weeks/year = $1040/year
