Tom's brother is 4 times as old as Tom's dog. If in 6 years, Tom's brother will be 30 years, how old is Tom's dog going to be in six years?
Let's think: If in six years Tom's brother will be 30 years old, he is currently 30 - 6 = 24 years old. Since Tom's brother is 4 times as old as Tom's dog, Tom's dog is 24 / 4 = 6 years old currently. Tom's dog will be 6 + 6 = 12 years old in six years.. The answer is: 12.

Nick has 60 cans. Each can takes up 30 square inches of space before being compacted and 20% of that amount after being compacted. How much space do all the cans take up after being compacted?
Let's think: First find the total amount of space the cans take up before being compacted: 60 cans * 30 sq in / can = 1800 sq in. Then multiply that amount by the percentage of space they take up after being compacted: 1800 sq in * 20% = 360 sq in.. The answer is: 360.

Jeremy listened to five fewer songs yesterday than today. Yesterday, he listened to nine songs. How many songs did Jeremy listen to in two days?
Let's think: Jeremy listened to 9 + 5 = 14 songs today. Thus, he listened to 9 + 14 = 23 songs in two days.. The answer is: 23.

Joe sells ham and cheese sandwiches for $1.50. If a slice of bread costs $0.15, a slice of ham costs $0.25 and a slice of cheese costs $0.35, how many cents does a sandwich with one slice of each protein cost Joe to make?
Let's think:
First find the cost of two slices of bread: $0.15 / slice * 2 slices = $0.30. Then add the cost of one slice each of ham and cheese: $0.30 + $0.25 + $0.35 = $0.90.. The answer is: 90.
