conversations.value: Solve the following math problem: Laura is hosting a carwash. She will charge $5 for a car, $6 for a truck, and $7 for an SUV. They raised $100 in total. If they washed 5 SUVs and 5 trucks, how many cars did they wash?

conversations.value: They earned $30 from trucks because 5 x 6 = 30
  They earned $35 from SUVs because 5 x 7 = 35
  They earned $35 from cars because 100 - 35 - 30 = 35
  They washed 7 cars because 35 / 5 = 7
