3(x-6)^4+11=15
3(x-6)^4=15-11
(x-6)^4=4/3
x-6 = +
or -![\sqrt[4]{4/3}](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B4%2F3%7D)

+6 or -
+6
x = 7.07 or 4.925
One sixth of an hour is 10 minutes.
That means it costs 5,700 every 10 minutes.
Costs 5,700 = 10 minutes
Dive 10 on both sides.
Costs 570 = 1 minute
Lets convert the minute into seconds.
Costs 570 = 60 seconds
Divide both sides by 60.
Costs 9.5 cents = 1 second
Round it off since you can't pay 9.5 cents.
Costs 10 cents = 1 second
This means that every second they pay 10 cents for the hotel. :D
