Baseon the analyst’s expectations, whiof the following best scribes the expectecompounannugrowth? A.Net sales will grow 15% annually annet income will grow 25% annually. B.Net sales will grow 20% annually annet income will grow 40% annually. C.Net sales will grow 25% annually annet income will grow 50% annually. A is correct.Using the genertime value of money formulfor sales, solve for r in the equation 2 = 1 × (1+r)5. For income, solve 3 = 1 × (1+r)5. Alternatively, using a financicalculator, for sales, enter N = 5, PV = 1, PMT = 0, FV = −2 ancompute I/Y. For income, change the FV to −3 anagain solve for I/Y. The solution for sales is 14.87%; anfor income is 24.57%. fv为什么用-的？
