Use reasoning to lead to the answer of the following question:
Alison has half as much money as Brittany. Brittany has 4 times as much money as Brooke. Brooke has twice as much money as Kent. If Kent has $1,000, how much money does Alison have?

4000
Brooke has 2 * 1,000 = 2,000 dollars.

Brittany has 4 * 2,000 = 8,000 dollars.

Alison has 8,000 / 2 = 4,000 dollars.

.

The answer: 4000
