Question: Peggy has 6 dolls. Her grandmother gives Peggy her own collection of 30 dolls. Over the year, Peggy receives half that amount of dolls between her birthday and Christmas. How many dolls does Peggy now have?
Answer: Step-by-step reasoning process: Peggy has 6 dolls and her grandmother gave her 30 so that’s 6 + 30 = 36 dolls. Over the holidays, Peggy is gifted half the number of dolls her grandmother gave her, so she receives 30 / 2 = 15 more dolls. Peggy had 36 dolls and received another 15 for a total of 36 + 15 = 51 dolls.
So the answer is 51.

Question: John decides to go back to school to get his PhD. He first takes 1 year of courses to get acclimated back to school life before starting his PhD. After that, he spends 2 years learning the basics of his field. He then starts research, and he spends 75% more time on research than he did learning the basics. He then spends half as long on writing his dissertation as his acclimation period. How long did it take him to do everything?
Answer: Step-by-step reasoning process: It took him 2 * .75 = 1.5 years longer to do his research than it took to learn the basics. So it took him a total of 2 + 1.5 = 3.5 years to do research. His dissertation took 1 / 2 = .5 years to write. So everything together took 1 + 2 + 3.5 + .5 = 7 years.
So the answer is 7.
