Part $3$

c$.$ Explain the value of the shadow price for the total investment constraint. If the student could borrow $$$$1$ comma $0001,000$ at $77\%$ a year to increase her total$$ investment, what would you recommend and$$ why?

Since the shadow price is $$$$0\mathrm{.}780\mathrm{.}78,$ every additional dollar invested will
