Answer:
1. The moon is bright enough for us to play outdoors.
2. I have enough money to pay this bill.
3. My sister is old enough to drive a car.
Step-by-step explanation:
"Enough" means sufficient. It can be used as a determiner, modifying a noun, or as an adverb, modifying a verb, an adjective, or another adverb.
The phrase or clause that contains "enough" can be followed by "to + verb":
- She is angry enough to hurt him.
- We have enough time to have a decent meal.
It can also be followed by the structure "for + object pronoun + to + verb", when we wish to indicate who will perform the action expressed by the verb:
- The day is warm enough for you to go to the beach.
- His house is close enough for me to walk there.
