Managing a line of credit: We want to complete the app that manages our line of credit at a bank. The line of credit allows us to carry a certain maximum negative balance of p. Negative balance will be charged an interest at a specified fixed rate x. A positive balance can lead to an interest accumulation at a different fixed rate y.

If the balance is greater than or equal to 50% but less than 80% of the line of credit, you should provide an amber alert. If the balance is greater than or equal to 80% of the line of credit, you should provide a red alert.
