To determine how many blocks east Mario is from his home after he finds his wallet, we can use the expression provided: \(7 + (-5)\).

1. When Mario walks 7 blocks east to the restaurant, he is at +7 blocks from his home.
2. When he retraces 5 blocks back, this is represented as -5 blocks.

Now, we can calculate the total distance east of his starting point:

\[
7 + (-5) = 7 - 5 = 2
\]

Thus, Mario is **2 blocks east** from his home after finding his wallet.

So, the answer is: Mario is **2 block(s)** east from his home.
