Question: Greg is riding his bike around town and notices that each block he rides, his wheels rotate 200 times. He's now on a a trail and wants to make sure he rides at least 8 blocks. His wheels have already rotated 600 times, how many more times do they need to rotate to reach his goal?
Answer: They need to rotate 1,600 times because 8 x 200 = 1,600. They need to rotate 1,000 more times because 1,600 - 600 = 1,000. The answer is 1000.
[Question]My cat's empty bowl weighs 420 grams. If I give my cat 60 grams per day and I always fill her bowl every 3 days, how much does her bowl weigh if after I ended up refilling her empty bowl she only ate 14 grams?
[Answer]If I give my cat 60 grams per day and I fill it to last 3 days, then I put a total of 60 * 3 = 180 grams into her bowl. If the empty bowl weighs 420 grams and I put 180 grams the total weight is = 420 + 180 = 600 grams. If my cat only ate 14 grams then the bowl right now weighs 600 - 14 = 586 grams. The answer is 586.
