A group of students is arguing about which are better terms for a loan with compound interest—longer time with lower interest, or shorter time with higher interest. They decide to write a program to calculate each total so that they can compare between both the conditions:

Question

principal = 10000
rate = 10.25
time = 5
Amount = principal * (pow((1 + rate / 100), time))
Total = Amount + principal
print("Compound interest is", Amount + principal)
rate = 5.25
time = 10
Amount = principal * (pow((1 + rate / 100), time))
print("Compound interest is", Amount + principal)
Which code should be placed into a function?

Responses

print("Compound interest is", Amount + principal)
print("Compound interest is", Amount + principal)

principal = 10000
principal = 10000

rate = 10.25
rate = 10.25

Amount = principal * (pow((1 + rate / 100), time))

Answer 1

To determine which part of the code should be placed into a function, we should look for the segment of code that is repeated or could be reused with different parameters. In the provided code snippets, the calculation of the amount using compound interest can be encapsulated in a function.

The code that calculates the total compound interest based on parameters for principal, rate, and time could be defined as a function.

Here's a suggested function encapsulation:

def calculate_compound_interest(principal, rate, time):
    Amount = principal * (pow((1 + rate / 100), time))
    Total = Amount + principal
    return Total

# Using the function
principal = 10000

# First condition
rate1 = 10.25
time1 = 5
print("Compound interest is", calculate_compound_interest(principal, rate1, time1))

# Second condition
rate2 = 5.25
time2 = 10
print("Compound interest is", calculate_compound_interest(principal, rate2, time2))

In this function, calculate_compound_interest, you can easily compute the total amount for any principal, rate, and time, making your code more modular and easier to maintain.

So among the provided options, the code block that handles the calculation of the total interest (which involves the principal, rate, and time) should be placed into a function.

Therefore, the correct choice for your question would be:

• Calculate the amount and print it (the calculation of Amount and Total can be encapsulated into a function).

Specifically, any of the following lines could be part of the function:

• Amount = principal * (pow((1 + rate / 100), time))
• Total = Amount + principal
• print("Compound interest is", Amount + principal)

But ideally, all of these should be wrapped into a function for better organization and reusability.
