Answer
2$\frac{1}{16}$ cases
Work Step by Step
Total track of the inventory ,$\frac{3}{8}$ of a case and 2 cases
Amount of baker potato used $\frac{5}{16}$ of a case
Potatoes in the kitchen when two 2 case orders are arrived = $\frac{3}{8}$ + 2 - $\frac{5}{16}$
=$\frac{3}{8}\times$ $\frac{2}{2}$ +$ 2 \times$ $\frac{16}{16}$ - $\frac{5}{16}$
=$\frac{6}{16}$ + $\frac{32}{16}$ - $\frac{5}{16}$
=$\frac{33}{16}$
=2$\frac{1}{16}$ cases
