It takes 12 hours to clean the windows of a certain office building. During the
first day of cleaning, the workers were able to clean for 9 hours. If the variable
t stands for the amount of time the workers have left to clean the windows,
which of the following units could apply to this variable?
O A. hours
O B. buildings
O C. Windows
OD. workers
The answer is A. Hours. If the variable t stands for the TIME the workers have left, then they have 3 HOURS left, so it would be hours. Hope this helped!
