Q: Two brick walls are being built. Each wall has 30 bricks in a single row and there are 50 rows in each wall. How many bricks will be used to make both walls?
A: Each brick wall needs 30 x 50 = 1500 bricks. Thus, the two walls need 1500 x 2 = 3000 bricks. The answer is 3000.

Q: On the first day of the journey, the Skipper sailed his ship halfway to the destination by traveling due east for 20 hours at a speed of 30 kilometers per hour, and then turned the ship's engines off to let them cool down. But while the engines were off, a wind storm blew his vessel backward in a westward direction. After the storm, the Skipper used his GPS device to determine the new location of the ship, and he discovered that he was only one-third of the way to his destination. How many kilometers had the ship been blown in a westward direction by the storm?
A: Traveling 20 hours due east at 30 kilometers per hour, the ship sailed 20 * 30 = 600 kilometers the first day. If half the distance to the destination is 600 kilometers, then 2 * 600 = 1200 kilometers is the total distance from start to destination. One - third of the distance from start to destination is 1 / 3 * 1200 = 400 kilometers. Thus, the wind storm blew the ship in a westward direction for 600 - 400 = 200 kilometers. The answer is 200.

Q: Hannah wanted to make an apple pie that would serve 8 people. She needed 2 pounds of apples that were on sale for $2.00 per pound. The pre-made pie crust cost $2.00. The lemon cost $.50 and the butter cost $1.50. How much did each serving of pie cost?
A:
2 pounds of apples at $2.00 / pound would cost 2 * 2 = $4.00. If we add all of the purchases together then the total bill was 4 + 2 + .50 + 1.50 = $8.00. There are 8 servings per pie. So $8.00 / 8 servings = $1.00 per serving. The answer is 1.
