Reasoning and answer: If Yola currently weighs 220 pounds, then Wanda, who weighs 30 pounds more than Yola, weighs 220 + 30 = 250 pounds. Wanda also weighs 80 pounds more than Yola did 2 years ago, meaning Yola weighed 250 - 80 = 170 pounds 2 years ago.
The answer: 170

If Susie puts 20% more money into her piggy bank, she'll have 20 / 100 * 200 = $40 more in her piggy bank. The total amount of money in Susie's piggy bank will increase to $200 + $40 = $240.
The answer: 240
Reverse engineering the question: Susie has $200 in her piggy bank. If she puts 20% more money into her piggy bank, how much money she will have?


Reasoning and answer: Ann had 3 dozen oatmeal cookies - 2 dozen = 1 dozen oatmeal cookies left. Ann had 2 dozen sugar cookies - 1.5 dozen = .5 dozen sugar cookies left. Ann had 4 dozen chocolate chip cookies - 2.5 dozen = 1.5 dozen chocolate chip cookies left. Ann has a total of 1 + .5 + 1.5 dozen cookies = 3 dozen cookies. 3 dozen cookies is 3 * 12 cookies = 36 cookies remaining.
The answer: 36

In round one, Jeff completed 16 - 1 = 15. In round two, Jeff completed 16 - 3 = 13. In round three, Jeff completed 16 + 4 = 20. In round four, Jeff completed 16 / 2 = 8. Jeff completed 15 + 13 + 20 + 8 = 56 skips in total. Jeff skipped an average of 56 / 4 = 14 skips per round.
The answer: 14
Reverse engineering the question: Sam and Jeff had a skipping competition at recess. The competition was split into four rounds. Sam completed 1 more skip than Jeff in the first round. Jeff skipped 3 fewer times than Sam in the second round. Jeff skipped 4 more times than Sam in the third round. Jeff got tired and only completed half the number of skips as Sam in the last round. If Sam skipped 16 times in each round, what is the average number of skips per round completed by Jeff?


Reasoning and answer: 12 mph faster than 60mph is 60 + 12 = 72 mph. 18 mph slower than 60 mph is 60 - 18 = 42 mph. If he spends 1 / 3 of the time at each of these three speeds, then he averages (60 + 72 + 42) / 3 = 58 mph.
The answer: 58

Question: Conner has a dune buggy that he rides in the desert. On flat sand, it can ride at a speed of 60 miles per hour. When traveling on downhill slopes, it can race at 12 miles per hour faster than it can when it is on flat sand. And when riding on an uphill inclined slow, it travels at a speed 18 miles per hour slower than when it is riding on flat sand. If Conner rides his dune buggy one-third of the time on flat sand, one-third of the time on uphill slopes, and one-third of the time on downhill slopes, what is his average speed in miles per hour?


Reasoning and answer: Each room can fit 2 * 2 + 1 = 5 students. Thus, the principal needs to book 30 / 5 = 6 rooms to fit everyone.
