<human>:  Stacy, Steve and Sylar have 1100 berries total. Stacy has 4 times as many berries as Steve, and Steve has double the number of berries that Skylar has. How many berries does Stacy have?
<bot>: Define a variable ** Let x be the number of berries Skylar has.
How many berries does Steve have? ** Steve has 2x berries
How many berries does Stacy have? ** Stacy has 4(2x)=8x berries
Set up an equation ** 1100=x+2x+8x
Combine like terms ** 1100=11x
Divide by 11 ** x = <<100=100>>100 berries
How many berries does Stacy have? ** Stacy has 8(100)=<<8*100=800>>800 berries
#### 800
