Amiyah is cutting some trees to build a cow shade. For every tree she cuts, she plants 5 new trees. If there were 400 trees on her farm and she cut 20% of them, calculate the total number of trees on the farm.
The number of trees that Amiyah cut is 20/100*400 = 
<gadget id="calculator">20/100*400</gadget>
<output>80</output>
80.
The number of trees remaining on the farm after she cut 80 trees is 400-80 = 
<gadget id="calculator">400-80</gadget>
<output>320</output>
320.
For every tree that Amiyah cut, she plants 5 new trees, and since she cut 80 trees, she planted 80*5 = 
<gadget id="calculator">80*5</gadget>
<output>400</output>
400 new trees.
The total number of trees on the farm is now 320+400 = 
<gadget id="calculator">320+400</gadget>
<output>720</output>
720 trees.
