At the end of year $0,$ FreshGo acquired YogurtToday at $$30$ million, including $$5$ million YogurtToday's debt.

FreshGo expects about $$500,000$ every year synergy from cost savings and cross$-$selling starting starting from the third year after closing $($year $3).$

After the merger, the cost of capital of the combined first is $5\mathrm{.}16\%$ and the tax rate is $40\%.$

Assuming the free cash flow from synergy will remain at this level in perpetuity $($as a going concern$),$ estimate the after tax present value of the anticipated

synergy $($in $$1,000).$

$5257$

None of these

$4754$

$4999$

I know the answer is $4999,$ but I$\text{'}$m trying to understand the steps to get there. Thank you!
