You work at an insurance agency. Your boss has asked you to purchase eight computer screens for the office. You are considering two online stores. The first store charges $629.99 total for the screens and offers free shipping. The second store charges $579.49 total for the same screens, and charges $39.99 for shipping all eight screens. Additionally, you have an online code for a $20 discount at the first store. What is the final cost for the store that offers the better deal?
