Quick TotaL

Incrementing Bills

Writing variable = variable + 5 feels too long for simple everyday changes. So developers commonly rely on += to add onto an existing number neatly. It also manages adding strings perfectly too!

The Assignment

You are updating a customer's payment total.

1. Make a variable total carrying the initialValue.
2. Add the amountToAdd exactly to total using +=.
3. Use += once more to attach " INR" string at the end of the total.
4. Return this formatted string.
