Final answer:
To pay back the plant cost by the end of year 5, the profits for years 0 to 5 need to sum to 0. We can calculate the required annual growth rate by breaking down the costs and revenues for each year. By solving an equation that sums the profits for each year, we can determine the annual growth rate needed to achieve the desired result.
Step-by-step explanation:
To pay back the plant cost by the end of year 5, the profits for years 0 to 5 need to sum to 0. We can break down the costs and revenues for each year to calculate the required annual growth rate (g).
- Year 0: Cost = $4 million
- Year 1: Revenue = 80,000 kits × $25 per kit
Variable costs = 50% of revenue
SG&A costs = 40% of revenue - Years 2 to 5: Revenue = Revenue from previous year × (1 + g)
Variable costs = 50% of revenue
SG&A costs = SG&A costs from previous year × (1 - 2%)
We can use the above information to set up an equation to solve for the annual growth rate (g). By summing the profits for each year and setting it equal to 0, we can solve for g. Once we find g, we can determine the annual growth rate needed to pay back the plant cost by the end of year 5.
