Two production groups produce the same part, the first group produces 120 less than the second group, it is known that the first group has 38 people, each produces 85 on average, and the second group has 25 people, how many pieces are each produced on average ? (list the equation)
两个生产小组生产同一种零件，第一小组比第二小组少生产120个，已知第一小组有38人，平均每人生产85个，第二小组有25人，平均每人生产多少个？(列出方程)
<gadget id="calculator">38 * 25</gadget>
<output>950</output>

<gadget id="calculator">950 + 120</gadget>
<output>1_070</output>

<gadget id="calculator">1_070 / 25</gadget>
<output>214/5 = around 42.8</output>

<result>214/5 = around 42.8</result>
