hope that the elementary school used 3000 kWh of electricity last month, and this month will save (1/10) compared with last month. If the electricity is 0.65 yuan per kWh, how much should I pay for this month?
希望小学上个月用电3000度，这个月比上个月节约(1/10)，如果每度电0.65元，这个月应付电费多少元？

<output>1/10 = around 0.1</output>

<gadget id="calculator">1 - (1/10)</gadget>
<output>9/10 = around 0.9</output>

<gadget id="calculator">3_000 * (9/10) * 0.65</gadget>
<output>1_755</output>

<result>1_755</result>
