Abie had 20 bags of chips. She gave 4 bags to her friend and bought another 6 bags of chips in the store. How many bags of chips does Abie have in the end?
Let's think: Abie had 20 - 4 = 16 bags of chips after giving 4 bags of chips to her friend. Abie has 16 + 6 = 22 bags of chips in the end.. The answer is: 22.

A bear eats up to 90 pounds of food per day to prepare for hibernation. If Victor weighs 126 pounds, how many "Victors" worth of food would a bear eat in 3 weeks?
Let's think: There are 3 x 7 = 21 days in 3 weeks. In 3 weeks, a bear would eat 90 x 21 = 1890 pounds of food. A bear would eat 1890 / 126 = 15 "Victors" worth of food in 3 weeks.. The answer is: 15.

Reuben opens a sandwich shop selling his namesake sandwich and pastrami sandwiches. Pastrami cost $2 more than the Reuben. He sells 10 Reubens and 5 Pastrami sandwiches and earns $55. How much does a pastrami sandwich cost?
Let's think: If X = "Price of Reuben" We know that 10(X) + 5(X + 2) = 55. Therefore 10X + 5X + 10 = 55. Therefore 15X = 45. Therefore, the price of a Reuben is $3 because 45 / 15 = 3. The price of pastrami is $5 because 3 + 2 = 5.. The answer is: 5.

Jack is stranded on a desert island. He wants some salt to season his fish. He collects 2 liters of seawater in an old bucket. If the water is 20% salt, how many ml of salt will Jack get when all the water evaporates?
Let's think:
First find how many liters of the seawater are salt: 2 liters * 20% = .4 liters. Then multiply that amount by 1000 ml / liter to find the number of ml of salt Jack gets: .4 liters * 1000 ml / liter = 400 ml.. The answer is: 400.
