Answer the following question.
A ship left a port and headed due west, having 400 pounds of food for the journey's supply. After one day of sailing, 2/5 of the supplies had been used by the sailors in the ship. After another two days of sailing, the sailors used 3/5 of the remaining supplies. Calculate the number of supplies remaining in the ship to last the sailors until they dock.
Step-by-step reasoning process: After one day of sailing, 2 / 5 * 400 = 160 pounds of food supplies had been used. The total number of supplies remaining in the ship is 400 - 160 = 240 pounds. After another 2 days of sailing, 3 / 5 * 240 = 144 pounds of food had been used. The total number of supplies remaining in the ship is now 240 - 144 = 96 pounds.
The answer is 96.

Answer 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?
Step-by-step reasoning process: 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.
The answer is 800.
