I took off $7$ points here.

Q$4$b $-$ the profit$/$loss $=$ gallons x $($spot price $-$

contract price Q$4$b$-$the profit$/$loss $=$gallons x $($spot price contract price$)=($$$1,299,300).$

Q$4$c $-$the interest on the floating $=$ $$900$M x $($BSTBY $+$ spread$)$; the interest on the fixed $=$$$900$M x $4\mathrm{.}5\%.$
