Answer:
24 hours
Step-by-step explanation:
Hi,
The equation to represent this situation would be 45x + 720 = 1800
(45 is the cost per hour, x is the number of hours since you don't know how many hours that person was there for. 720 is there because no matter what, you have to pay 720 to visit and = 1800 is the total cost)
Now, solve for x.
45x + 720 = 1800
Subtract 720 on both sides...
45x = 1080
Divide by 45 on both sides...
x = 24
