ABC is considering two investment alternatives. Alternative A requires an initial investment of $10,000; it will yield incomes of $3000, $3500, $4000, and $4500 over its 4-year life. Alternative B requires an initial investment of $12,000; it is anticipated that the revenue received each year will increase at a rate of 8%/year (each year's revenue is 8% higher than that of the preceding year). Based on an interest rate of 10% compounded annually, what must be the revenue at the first year for B in order for alternatives A and B to be equivalent? (Draw the cash flow profiles)
