Shtirlitz [24]

Answer:

Written in Python

cost = float(input("Cost of one room: "))

numrooms = int(input("Number of rooms: "))

days = int(input("Number of days: "))

salestax = float(input("Sales tax (%): "))

print("Cost of one room: "+str(cost))

print("Discount: 0%")

print("Number of rooms: "+str(numrooms))

print("Number of days: "+str(days))

totalcost = numrooms * cost

print("Total cost: "+str(totalcost))

salestax = salestax * totalcost/100

print("Sales tax: "+str(salestax))

print("Total Billing: "+str(salestax + totalcost))

Explanation:

The next four lines prompts user for inputs as stated in the question

<em>cost = float(input("Cost of one room: "))</em>

<em>numrooms = int(input("Number of rooms: "))</em>

<em>days = int(input("Number of days: "))</em>

<em>salestax = float(input("Sales tax (%): "))</em>

<em />

The following line prints cost of a room

print("Cost of one room: "+str(cost))

The following line prints the discount on each room (No information about discount; So, we assume it is 0%)

print("Discount: 0%")

The following line prints number of rooms

print("Number of rooms: "+str(numrooms))

The following line prints number of days

print("Number of days: "+str(days))

The following line calculates total cost of rooms

totalcost = numrooms * cost

The following line prints total cost

print("Total cost: "+str(totalcost))

The following line calculates sales tax

salestax = salestax * totalcost/100

The following line prints sales tax

print("Sales tax: "+str(salestax))

The following line calculates and prints total billings

print("Total Billing: "+str(salestax + totalcost))
