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?
The school bought 2 x 2 = 
<gadget id="calculator">2*2</gadget>
<output>4</output>
4 dinosaur models for the elementary library.
So the school bought a total of 2 + 4 = 
<gadget id="calculator">2+4</gadget>
<output>6</output>
6 models.
The price of each model was reduced by $100 x 5/100 = $
<gadget id="calculator">100*5/100</gadget>
<output>5</output>
5.
Thus, each model cost $100 - $5 = $
<gadget id="calculator">100-5</gadget>
<output>95</output>
95.
Therefore, the school paid a total of $95 x 6 = $
<gadget id="calculator">95*6</gadget>
<output>570</output>
570.
