<span>THE AREA OF THE ROOM IS :A=4*2.4=9.6 m^2
THICKNESS t=0.30 m
DIFFERENCE IN TEMPERATURE dT=18-6=12
q=kAdT/dx=kA*dT/t
q=1.3(9.6)(12)/0.30=4992 W=499.2 J/s
In 1 hour or 3600 sec
P=q*T=(499.2 J/s)(3600 s)=1797120 J=1.8 MJ
1.8MJ OF HEAT FLOWS HTROUGH THE WALL IN ONE HOUR</span>
The total amount for food and drinks is: $51.26
The 7% tax is: 51.26 * 0.07 = $3.5882
The 20% tip is: 51.26 * 0.2 = $10.252
Your total amount is: 51.26 + 3.5882 + 10.252 = $65.1002 or rounded $65.10
Hope this helped!
