Q: Blanch has 15 slices of pizza in the fridge. During breakfast, she eats 4 slices. At lunch, Blanch eats 2 slices, then takes two slices as a snack. Finally, she consumes 5 slices for dinner. How many slices of pizza are left?
A: 2
Step-by-step reasoning process: During breakfast, Blanch has 15 - 4 = 11 slices left. At lunch, she still has 11 - 2 = 9 slices left. After the snack, there are still 9 - 2 = 7 slices left. Finally after dinner, Blanch has 7 - 5 = 2 slices left.


Q: The age of a lioness in a park is twice the age of a hyena in the same park. The lioness is 12 years old. If the babies of the two animals are half the age of their mothers, calculate the sum of the age of the babies in five years.
A: 19
Step-by-step reasoning process: If the lioness is 12 years old, the hyena, half her age, is 12 / 2 = 6 years old. The baby of the lioness is 12 / 2 = 6 years old, half the mother's age. Five years from now, the age of the lioness's cub will be 6 + 5 = 11. The baby of the hyena is 6 / 2 = 3 years old, which is half the mother's age. The hyena's baby will be 3 + 5 = 8 years old in five years. Together, the total age of the babies will be 8 + 11 = 19 years in five years.
