Assume the same buyer as in question $1$ and that storage cost for corn between December $1,2023$ and March $1,2024$ is $$\frac{0\mathrm{.}15}{?}$ bu$.$ What would his net purchase price $($cost$)$ for the corn be if:

a$.$ He bought the physical corn on $\frac{12}{1}\frac{?}{23}$ in the cash market when the local cash price was

$$\frac{5\mathrm{.}18}{b}u.?$

b$.$ He hedged $($long position$)$ the corn on $8/3\frac{?}{23}$ and then offsets the contract on $\frac{03}{01}\frac{?}{24}$ when local cash price is $$\frac{5\mathrm{.}33}{b}u.$ and the March Corn futures price is $$\frac{5\mathrm{.}23}{b}u.?$

c$.$ He waited to purchase the corn on $\frac{03}{01}\frac{?}{23}$ when the basis was $$0\mathrm{.}10$ over per bushel and the futures price was $$\frac{5\mathrm{.}18}{b}u.$
