Answer:
Nathanial will charge $12
Step-by-step explanation:
If he charges $3 per 15 minutes, one hour is 60 minutes. And 60 divided by 15 is 4 so you do 3x4 because he charges $3 per 15 minutes.
12$ an hour
60 minutes in an hour 15 times 4= 60 which is one hour, so 4 times 3 equals 12 which is the answer
