Question: 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. Think carefully first, then make a decision:
The number of trees that Amiyah cut is 20 / 100 * 400 = 80. The number of trees remaining on the farm after she cut 80 trees is 400 - 80 = 320. For every tree that Amiyah cut, she plants 5 new trees, and since she cut 80 trees, she planted 80 * 5 = 400 new trees. The total number of trees on the farm is now 320 + 400 = 720 trees. So the answer is 720.
