1.13 Create an equation for total revenue that combines time-to-market and NRE/unit cost considerations. Use the revenue model of Figure 1.4(b). Assume a 100-month product lifetime, with peak revenue of $100,000 month. Compare use of a general-purpose processor having an NRE cost of $5,000, a unit cost of $30, and a time-to-market of 12 months (so only 88 months of the product's lifetime remain), with use of a single. purpose processor having an NRE cost of $20,000, a unit cost of $10, and a time-to- market of 24 months. Assume the amount added to each unit for profit is $5. 1.14 Using a spreadsheet, develop a tool that allows us to plug in any numbers for problem 1.13 and generates a revenue comparison of the two technologies
