Answer
Initial values $\qquad \ \ \ $ R = 20 $\qquad \ \ \ \ $ memory location 80 = 43
$\qquad \qquad \qquad \qquad \qquad \qquad \qquad $memory location 81 = 97
$\begin{array}{llll}
{\text {Memory}} & {\text {Final Contents} } & {\text {Final Contents} } & {\text {Final Contents} }\\
{\text {Operation }} & {\text {of Register R} } & {\text {of Mem Loc 80} } & {\text {of Mem Loc 81} }\\
{\text {STORE 81} } & {\text {20}} & {43} & {\text {20}} \\
\end{array}$
