Mickey's number is greater than Jayden's number by exactly 20. If Jayden's number is 40 less than Coraline's number, and Coraline's number is 80, calculate the total of the numbers they have.
Let's think: If Coraline has the number 80, Jayden, whose number is 40 less than that of Coraline, has 80 - 40 = 40. Together, Jayden and Coraline's numbers total 80 + 40 = 120. Mickey's number is greater than Jayden's number by exactly 20, meaning his number is 40 + 20 = 60. The total of the numbers the three have is 120 + 60 = 180.. The answer is: 180.

Colin can skip at six times the speed that Brandon can. Brandon can skip at one-third the speed that Tony can. And Tony can skip at twice the speed that Bruce can. At what speed, in miles per hour, can Colin skip if Bruce skips at 1 mile per hour?
Let's think: Tony can skip at twice the speed that Bruce can, for a speed of 1 * 2 = 2 miles per hour. Brandon can skip at one - third the speed that Tony can, for a speed of 2 * (1 / 3) = 2 / 3 miles per hour. Colin can skip at six times the speed that Brandon can, for a speed of (2 / 3 * 6 = 4 miles per hour).. The answer is: 4.

Clive is buying olives for dinner. He has $10 to spend and needs 80 olives. A jar of 20 olives costs $1.50. How much change will Clive have when he buys what he needs?
Let's think: He needs 4 jars of olives because 80 / 20 = 4. He will spend $6 because 4 x 1.5 = 6. He will have $4 in change because 10 - 6 = 4.. The answer is: 4.

Beth is looking at her book collection and is wondering how many comic books she owns. She has 120 books and 65% are novels. 18 are graphic novels. The rest are comic books. What percentage of comic books does she own?
Let's think:
The proportion of graphic novels is .15 because 18 / 120 = .15. The percentage of graphic novels is 15 because 100 x .15 = 15. The percentage of comic books is 20 because 100 - 65 - 15 = 20.. The answer is: 20.
