The day before Gerardo returned from a two-week trip, he began to wonder whether he left his plants inside his apartment or outside on his deck. He knows these facts:
If his plants are indoors, he must water them at least once a week or they will die.
If his plants are outdoors and it rains, then he does not have to water them. Otherwise, he must water them at least once a week or they will die.
It has not rained in his town for two weeks.
When Gerardo returns, will his plants be dead? Explain your reasoning.
First consider each scenario separately.
If he left his plants indoors for two weeks what would happen?
If he left his plants outdoors for two weeks, and it did not rain, what would happen?
If his plants are indoors... They will be dead because he did not water them once a week.
If his plants are outdoors... They will be dead because it did not rain.
Yes, Gerardo's plants will be dead.
