When you add up the temperature for the entire week, it comes to 40 + 50 + 65 + 36 + 82 + 72 + 26 = 371. These temperatures were over 7 days so the average temperature was 371 / 7 = 53 degrees.
The answer: 53
Reverse engineering the question: September's temperature fluctuated severely in 1 week. They started off with 40 degrees on Sunday then hit 50 on Monday, 65 on Tuesday, 36 on Wednesday, 82 on Thursday, 72 on Friday and ended the week at 26 on Saturday. What was the average temperature for that week?
Reasoning and answer: They need 1600 square feet / 400 square feet / gallon = 4 gallons of paint for their walls. Since they will do a second coating, then they would need 4 gallons x 2 = 8 gallons in all. Eight gallons of paint will cost $45 / gallon x 8 gallons = $360. Thus, Jason and Jeremy will each contribute $360 / 2 = $180.
The answer: 180
What was the question?
Question: Jason and Jeremy want to paint their wall white and agreed to split the cost of the paint. A gallon of paint costs $45 and can cover up to 400 square feet. How much will each of them contribute to the cost of the paint if their walls have a total area of 1600 square feet and will need a second coat?
The price per egg in a tray is $12 / 30 eggs = $0.4 / egg. The equivalent of $0.4 in cents is $0.4 x 100 cents / dollar = 40 cents. Hence, you can save 50 cents - 40 cents = 10 cents per egg if you buy a tray.
The answer: 10
Reverse engineering the question: The price per organic egg is 50 cents. The price of a tray of eggs that contains 30 eggs is $12. How much can you save, in cents, per egg if you buy a tray versus individual eggs?
Reasoning and answer: Derek has 40 - 14 - 11 - 5 = 10 dollars left. Dave has 50 - 7 = 43 dollars left. Dave has 43 - 10 = 33 more dollars left than Derek.
The answer: 33
What was the question?
Question: Derek has $40. He spends $14 on lunch for himself, $11 for lunch for his dad, and $5 on more lunch for himself. His brother Dave has $50 and only spends $7 on lunch for his mom. How much more money does Dave have left than Derek?
Each animal has 1 + 3 = 4 total heads and legs. Then there are 20 / 4 = 5 in the flock.
The answer: 5
Reverse engineering the question: The tripodasaurus has three legs. In a flock of tripodasauruses, there is a total of 20 heads and legs. How many tripodasauruses are in the flock?
Adam can make 15 x 3 = 45 figurines out of the blocks of basswood. He can also make 3 x 2 = 6 figurines out of a block of Aspen wood. So, he can make 20 x 6 = 120 figurines out of all the blocks of Aspen wood. He can also make 20 x 4 = 80 figurines out of all the blocks of butternut wood. Therefore, Adam can make a total of 120 + 80 + 45 = 245 figurines using all the blocks of wood.
The answer: 245
Reverse engineering the question:
Adam owns a wood carving shop, if a block of basswood can create 3 figurines and a block of butternut wood can create 4 figurines, and a block of Aspen wood can make twice the amount of figurines compared to basswood, how many figurines can he make if he owns 15 blocks of basswood, 20 blocks of butternut wood, and 20 blocks of Aspen wood?
