Reasoning and answer: Three sets of toy organizers cost $78 x 3 = $234. Two gaming chairs cost $83 x 2 = $166. Leon's total orders amount to $234 + $166 = $400. Then, the delivery fee is $400 x 5 / 100 = $20. So, Leon had to pay a total of $400 + $20 = $420.
The answer: 420

Reasoning and answer: First divide 32 by 3, ignoring the remainder, to find how many chapters in the book are divisible by 3: 31 / 3 = 10.33..., which means 10 chapters are divisible by 3. Then subtract that number from the total number of chapters to find how many chapters she reads: 31 chapters - 10 chapters = 21 chapters. Then multiply the number chapters by the time to read each chapter to find the total time she spends reading: 21 chapters * 20 minutes / chapter = 420 minutes. Then divide that time by the number of minutes per movie to find the total time spent reading in hours: 420 minutes / 60 minutes / hour = 7 hours.
The answer: 7
