Step 1: Compute $52 + 28$ .

Add the ones place: $2 + 8 = 10$ . Write $0$ , carry $1$ .

\begin{array}{r@{}r@{}r}
  & 5 & 2 \\
+ & 2 & 8 \\
\hline
  &   & 0 
\end{array}

Add the tens place: $5 + 2 + 1 = 8$ .

\begin{array}{r@{}r@{}r}
  & 5 & 2 \\
+ & 2 & 8 \\
\hline
  & 8 & 0 
\end{array}

So, $52 + 28 = 80$ .

Step 2: From the balance scale picture, $\text{lb} + 50 = 70$ .

Subtract: $\text{lb} = 70 - 50$ .

$70 - 50 = 20$ .

So, $\text{lb} = 20$ lb.

Step 3: Compute $\text{lb} + 25 = 20 + 25$ .

Add the ones place: $0 + 5 = 5$ .

Add the tens place: $2 + 2 = 4$ .

\begin{array}{r@{}r@{}r}
  & 2 & 0 \\
+ & 2 & 5 \\
\hline
  & 4 & 5 
\end{array}

So, $20 + 25 = 45$ lb.

45 lb
