Hello, I need the breakdown of this formula: $$126,000/(1+0\mathrm{.}08)+$ $$126,000/(1+0\mathrm{.}08)^2+$ $$126,000/(1+0\mathrm{.}08)^3+$ $$126,000/(1+0\mathrm{.}08)^4-$ $$400,000$ NPV $$ $$97,158\mathrm{.}58$$$126,000/(1+0\mathrm{.}08)+$ $$126,000/(1+0\mathrm{.}08)^2+$ $$126,000/(1+0\mathrm{.}08)^3+$ $$126,000/(1+0\mathrm{.}08)^4-$ $$400,000$ NPV $$ $$97,158\mathrm{.}58$
