Eddy's spider plant produces 2 baby plants 2 times a year. After 4 years, how many baby plants will the mother plant have produced?
Thoughts? Step-by-step reasoning:
The mother plant produces 2 baby plants 2 times a year so it produces 2 * 2 = 4 plants a year. It produces 4 plants a year so after 4 years it will produce 4 * 4 = 16 baby plants.
Thus, the answer is 16.
