James has 3 more than 2 times the number of Oreos Jordan has. If there are 36 Oreos total, how many does Jordan have? Give the rationale and then the answer.
Let's think step by step. Let x represent the number of Oreos Jordan has. James:3 + 2x Oreos. Total:3 + 2x + x = 36. 3x + 3 = 36. 3x = 33. x = 11 Oreos.. The answer is: 11.

Cameron drives at twice the speed of his brother, Chase. But Danielle drives at three times the speed of Cameron. If it takes Danielle 30 minutes to travel from Granville to Salisbury, how long, in minutes, will it take Chase to travel from Granville to Salisbury? Give the rationale and then the answer.
Let's think step by step. If Danielle drives at three times the speed of Cameron, it will take Cameron 30 * 3 = 90 minutes for Cameron to travel the same distance. And since Cameron drives at twice the speed of his brother, Chase, it will take Chase 90 * 2 = 180 minutes to travel from Granville to Salisbury.. The answer is: 180.

A vampire needs to suck 7 gallons of blood per week to survive. If he sucks 2 pints of blood per person, how many people does he need to suck each day to survive? Give the rationale and then the answer.
Let's think step by step. Each day it needs to consume 7 / 7 = 1 gallon of blood. There are 128 / 16 = 8 pints per gallon. So he needs to suck blood from 8 / 2 = 4 people per day.. The answer is: 4.
