Matt has an apple tree. Apple thieves steal that half of the apples on the tree on every night of the week (7 times). How many apples were originally on the tree, if there is only one apple left on the tree after the thieve last raid?
:
Let a = original number of apples on the the tree
a*.5^7 = 1
a * .0078125 = 1
a = 1%2F.0078125
a = 128 apples
