You want the total volume of a cuboid 1" × 10" × 38" and a cylinder 1" in diameter by 12" long.
Volume of a cuboid:
.. V = l*w*h
.. = (38")*(10")*(1")
.. = 380 in³
Volume of a cylinder:
.. V = (π/4)*d²*h
.. = (3.14/4)*(1")²*(12")
.. = 9.42 in³
Total volume = Volume of cuboid + Volume of cylinder
.. = 380 in³ +9.42 in³
.. = 389.42 in³
The volume of the coat rack is approximately 389.42 in³.
The answer is 9.45.
How to do it:
First you have to find 20 percent of 7.50. You do .20*7.50 which equals 1.5. Then you subtract 1.5 from 7.5 which equals 6. Now you need to add the tax. Do 6*0.0575 which equals 3.45. Finally you add 3.45 to 6 which gets the answer: 9.45
If she pays in advance: C = 5 ((89n - 5n) + (35n + 4n))
If she doesn't pay in advance: C = 5 (89n + (35n + 4n))
(Where n = day or night and C = cost [for rental car and hotel])
