Relative information!

A Roth IRA and a traditional IRA differ in that taxes are paid on the income that is contributed to a Roth IRA, but the withdrawals at retirement are tax$-$free. On the other hand, contributions to a traditional IRA reduce your taxable income, but the withdrawals at retirement are taxable. Assuming you intend to allocate $$5,000$ per year for retirement savings, you will retire in $30$ years and expect to live for an additional $20$ years after retirement.

a$.$ If you decide to save in a traditional IRA, and assuming a fixed tax rate of $30\%,$ what would be your $20-$year retirement consumption stream after$-$tax? Let's assume the before$-$tax interest rate is $5\%.$ Your answers should be rounded off to two decimal places.

b$.$ If you opt to save in a Roth IRA, what would be your consumption stream during your $20-$year retirement period? Please round up your answers to two decimal places.
