B. Most new technologies are replaced within a few months.
C. A business should wait for its competitors to try out a new technology, before trusting it.
D. The price of the new technology might decrease as it becomes more common
Answer:
D. The price of the new technology might decrease as it becomes more common
Explanation:
The price of the new technology might decrease as it becomes more common. The correct option is D.
One of the primary explanations for why a company should think twice before investing in cutting-edge technology is the likelihood that the cost may go down in the future.
Due to its novelty and restricted availability, new technologies frequently have higher prices when they are first introduced.
But as time goes on and the technology is more commonly used, there is more competition, which drives down costs and provides more cheap possibilities.
Businesses can save money and better utilise their resources by waiting for the price to drop.
As a result, they are more equipped to assess the technology's utility and its suitability for their particular requirements and objectives.
Thus, the correct option is D.

You’ve been hired to help a bank automate their deposit/withdrawal system! Your task is to write a Python program that interacts with a customer in order to process a deposit or withdrawal.
Assume the customer has an initial balance of $1000 (you should store the number 1000 in a variable). Then, ask the user two things:
Whether they want to make a deposit or withdrawal
For this step, they should type a deposit or withdrawal, depending on what they want to do. It needs to be the exact spelling, including capitalization!
How much money they want to deposit or withdraw
For this step, they should enter an integer.
Then, your program should use an if/elif/else statement to do the following:
If the customer is making a deposit, add the amount to their balance.
If the customer is making a withdrawal, subtract the amount from their balance.
If the customer typed something other than "deposit" or "withdrawal", print "Invalid transaction.".
In this case, the customer’s final balance is just the same as their initial balance.
Finally, your program should use an if/else statement to do the following:
If the customer’s final balance would be negative (less than zero), tell them "You cannot have a negative balance!".
Otherwise, report their final balance.
Here are some examples of what running your program should look like:
Example 1:
Deposit or withdrawal: withdrawal
Enter amount: 500
Final balance: 500
Example 2:
Deposit or withdrawal: withdrawal
Enter amount: 1500
You cannot have a negative balance!
Example 3:
Deposit or withdrawal: deposit
Enter amount: 500
Final balance: 1500
Answer: See below
Explanation:
Description: In this program, read-option from the user and based on that, perform the operation. And display the balance if the balance is negative.
transactions.py
balance = 1000
#read options from the user
option = input("Deposit or withdrawal: ")
amount = 0
#check if option is a withdrawal
if option == 'withdrawal':
amount = int(input("Enter an amount: "))
balance = balance - amount
#check option is deposit
elif option == 'deposit':
amount = int(input("Enter an amount: "))
balance = balance + amount
else:
print("Invalid transaction.")
#check balance is less than 0 (negative)
if balance < 0:
print("You cannot have a negative balance!")
else:
print("Final balance:",balance)
