Answer this question:Sidney has 4 kittens and 3 adult cats. She has 7 cans of cat food. Each adult cat eats 1 can of food per day. Each kitten eats 3/4 of a can per day. How many additional cans of food does Sidney need to buy to feed all of her animals for 7 days.
Sidney has 3 adult cats * 1 can of food = 3 cans of food per day. Sidney's adult cats will need 3 cans * 7 days = 21 cans for the week. Sidney has 4 kittens * 3 / 4 cup of food = 3 cans of food per day. Sidney's kittens will need 3 cans * 7 days = 21 cans for the week. Sidney will need to buy 21 cans + 21 cans - 7 cans = 35 cans.
The answer is 35.

Answer this question:A cargo ship moving from Shanghai to Vancouver navigates for 21 days before reaching port. Customs and regulatory processes in Vancouver last 4 days. Finally, moving the cargo from the port to your rural warehouse takes some time and it always arrives on the seventh day. How many days ago should the ship have departed if your warehouse is expecting the shipment 2 days from today?
The total lead time for the cargo is 21 days on water + 4 in customs + 7 to the warehouse or 21 + 4 + 7 = 32 days. If the warehouse is expecting the cargo in 2 days from today then the cargo should have already completed 32 - 2 = 30 days of lead time.
The answer is 30.

Answer this question:Kevin has a tree growing in his garden that is currently 180 inches tall. That is 50% taller than it was when he planted it there. How tall was the tree, in feet, then?
Since it is 50% taller, then 180 inches is 100% + 50% = 150% of its height then. So each 1% is equal to 180 / 150 = 1.2 inches. So, its height then was 1.2 x 100% = 120 inches. Since 1 foot is equal to 12 inches, then 120 inches is equal to 120 / 12 = 10 feet.
The answer is 10.

Answer this question:Vincent has 72 inches of rope that he wants to use for a project, but he needs to cut it into smaller pieces first. He cuts it into 12 equal length pieces, but then he realizes it's too short, so he ties three pieces together. The knots then make each piece 1 inch shorter. How long are his pieces of rope after all this?
Each small piece is 6 inches because 72 / 12 = 6. Each piece is then 5 inches long after the knots are tied because 6 - 1 = 5. The three pieces tied together are now 15 inches long because 5 x 3 = 15.
The answer is 15.
