Need help with part b$,$ cant get the right answer: Prof. Business has a self$-$managed retirement plan through her University and would like to retire in $13$ years and wonders if her current and future planned savings will provide adequate future retirement income. Here are her information and goals.

Prof. Business wants a $23-$year retirement annuity that begins $13$ years from today with an equal annual payment equal to $$90,000$ today inflated at $2\mathrm{.}5\%$ annually over $13$ years. Her first retirement annuity payment would occur $13$ years from today. She realizes her purchasing power will decrease over time during retirement.

Prof. Business currently has $$400,000$ in her University retirement account. She expects these savings and any future deposits into her University and any other retirement account will earn $7\mathrm{.}5\%$ compounded annually. Also, she expects to earn this same $7\mathrm{.}5\%$ annual return after she retires.

Answer the following questions to help Prof. Business finalize her retirement planning.

A$)$ What is Prof. Business$$ desired annual retirement income?

FV $=$ $$90000*(1+0\mathrm{.}025)^13=124065\mathrm{.}994$

B$)$ How much will Prof. Business need $13$ years from today to fund her desired retirement annuity?

PV $=?$ N $=23$ I$/$R $=7\mathrm{.}5$ PMT $=124065\mathrm{.}99$

$=1340742\mathrm{.}61($incorrect$)$

i saw the correct answer, it was $$1\mathrm{.}4$ million something i forgot the specifics, not $1\mathrm{.}3$ like i got though. i use a financal calcualtor so idont need a big formula for this.
