3. In order to ascend a skyscraper and see the city view from a height, each visitor is
required to purchase an entrance ticket. The price of this entrance ticket is vary based
on several conditions as follow:
If the visitor is a student, then the visitor will get a 20% discount from the total price
of an entrance ticket.
If the visitor is going to ascend the skyscraper on a weekend or a holiday, then the
ticket price is 20% more expensive than the regular one.
What are the variables needed to create a program that could calculate the total ticket
price that must be paid by a visitor of this skyscraper? (list out all possible variables
and the data type for each variable)
Jawab :
hargaTiket  integer
jumlahTiket integer

, tipeCustomerstring
discount integer
waktuPergi string


4. Provided below are user input variables:
a. QTS (int)
b. midTerm (int)
c. QAS (int)
d. finalTerm (int)
Create an application to calculate the Final Score.
nts = 35% QTS + 65% midTerm
nas = 35% QAS + 65% finalTerm
finalScore = 40% nts + 60% nas




5. Provided below are user input variables:

, price (int)
payment (int)
Create an application to calculate the Change Money.
changeMoney = payment – price




6. Provided below are user input variables:
totalItem (int)
price (int)
Create an application to calculate the Total Payment.
totalPayment = price * totalItem
