If hospital ICU room rates are $784.00 per day, how many days was a patient in ICU if their total room charge is $10,192.00?​
babunello [35]
Answer:
13 days
Step-by-step explanation:
The easiest way to calculate this is to take the total room charge ($10,192.00) and divide by the room rate per dayday ($784.00). This equation looks like 10,192 ÷ 784 = 13
This works out because you are just trying to see how many times that one day charge will fit into the total cost charge.

Hope this helps you out. If you have any questions feel free to comment! :)
