Ms$.$ Prince wants to create a scholarship in honor of her parents at the law school from which

she received her degree. She could endow the scholarship with $$647,500$ cash or with

$$647,500$ worth of marketable securities with a cost basis of $$388,500.$ Assume the taxable year

is $2024.$

Required:

If her AGI is $$3\mathrm{.}8$ million, compute the after$-$tax cost of the two endowment options. Use

Individual Tax Rate Schedules and Tax rates for capital gains and qualified dividends.

Note: Enter your answers in dollars not in millions of dollars.

I am just not understanding what rates to use and when.
