Use reasoning to lead to the answer of the following question:
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?

800
Let x be the number of berries Skylar has.

Steve has 2x berries.

Stacy has 4(2x) = 8x berries.

1100 = x + 2x + 8x.

1100 = 11x.

x = 100 berries.

Stacy has 8(100) = 800 berries.

.

Final answer: 800
