What is the cost of the room for that is used for 1.5 hours at the rate of $23 per month room and size of 288 sg ft?
I don't know how the size of the room (288 sq ft) has to do with the rate. Is it related?
A month can vary between 28-31 days, so it is difficult to convert days to hours.
1.5/hours in a month = x/$23
I hope this helps.
