Sam owns a home-based embroidery business. He is considering buying a new sewing and embroidery machine. The Janome Memory Craft 14000 Sewing and Embroidery Machine bundle is priced at $6500 and will save approximately 30 hours of time (valued at $20 per hour). As an alternative, Sam estimates purchasing the newer Janome MB-4S Four Needle Embroidery Machine will save approximately 60 hours of time (valued at $20 per hour). Both models have the same annual maintenance costs. Based on the true economic value, how much should Sam be willing to spend on the Janome MB-4S?
