Q: Denmark wants to order pizza. For toppings, he has 3 cheese, 4 meat and 5 vegetable options, one of which is peppers. He can have only one selection from each topping category (one cheese, one meat and one vegetable). However, if he chooses to have pepperoni, he cannot have peppers. How many topping combinations does he have total?
A: Permutate the ingredients. 3 cheeses * 4 meats * 5 vegetables = 60 choice. However, we must take out the combinations that could have pepperoni and peppers, 1 cheese + 1 meat * + 1 vegetable = 3 bad choices. 60 - 3 = 57 choices. The answer is 57.
Question: Cindy can jump rope for 12 minutes before tripping up on the ropes. Betsy can jump rope half as long as Cindy before tripping up, while Tina can jump three times as long as Betsy. How many more minutes can Tina jump rope than Cindy?
Answer:
Betsy jumps half as long as Cindy, who jumps for 12 minutes so Betsy jumps 12 / 2 = 6 minutes. Tina jumps three times as long as Betsy, who jumps for 6 minutes so Tina jumps 3 * 6 = 18 minutes. Tina can jump for 18 minutes and Cindy and jump for 12 minutes so Tina can jump 18 - 12 = 6 minutes longer. The answer is 6.
