compute desired balance in ruby

To compute the desired balance in Ruby, you need to start with the initial balance and apply any transactions or calculations to it. Here's an example that demonstrates how you can do this:

main.rb
# Initial balance
balance = 1000

# Transactions
transaction1 = 500
transaction2 = -200
transaction3 = 300

# Add or subtract transactions from the balance
balance += transaction1
balance += transaction2
balance += transaction3

# Print the desired balance
puts "Desired balance: $#{balance}"
293 chars
16 lines

In this example, the initial balance is set to 1000. Then, there are three transactions: transaction1 adds 500 to the balance, transaction2 subtracts 200, and transaction3 adds 300. Finally, the desired balance is printed.

You can customize this example by updating the values of the initial balance and transactions to fit your specific needs.
