conversations.value: Can you explain how to solve this math problem: The Science museum sells dinosaur models for $100 each. A certain school bought 2 models for the kindergarten library and also bought twice as many for the elementary library. Since the school bought more than 5 models, there was a 5% reduction in price for each model. How much did the school pay in all?

conversations.value: The school bought 2 x 2 = 4 dinosaur models for the elementary library.
  So the school bought a total of 2 + 4 = 6 models.
  The price of each model was reduced by $100 x 5/100 = $5.
  Thus, each model cost $100 - $5 = $95.
  Therefore, the school paid a total of $95 x 6 = $570.
