(Round your answers to \\( \\mathbf{2} \\) decimal place.) b. What will be your 20 -year retirement consumption stream if you choose to save in a Roth IRA? (Round your answers to 2 decimal place.) c. Which provides better expected results if you expect your tax rate to decrease from \30 today to \25 at retirement? Traditional IRA Roth IRA
