To determine how much Bailey will spend altogether on her lunch, we need to know the cost of the lunch itself. However, since the cost of the lunch is not provided in your question, we cannot accurately calculate the total amount Bailey will spend.
If you have the cost of the lunch, we can perform the calculation using this formula:
Total Amount Spent = Cost of Lunch + Delivery Fee + Tip
If you provide the cost of the lunch, I can help you calculate the total amount Bailey will spend.
