Rod adds the prices of three grocery bills to get a total of $38 + $44 + $52= $82 + $52 = $134. What is another way that Rod can add the bills and get the same total?

Rod's original addition method was:

\[
38 + 44 + 52 = 82 + 52 = 134
\]

Another way to add the bills could be by pairing the numbers differently. For instance:

\[
(38 + 52) + 44 = 90 + 44 = 134
\]

This approach reorganizes the way the numbers are grouped but still leads to the same total.
