To find the total number of contacts, we need to add up the numbers listed for each person.
Step 1: List the numbers
* Walter: 112
* Jose: 104
* Victor: 94
* Heather: 154
* Sandy: 135
* Sara: 98
Step 2: Add them together
Let's add them in pairs to make it easier:
1. $112 + 104 = 216$
2. $94 + 154 = 248$
3. $135 + 98 = 233$
Now, add those three results together:
4. $216 + 248 = 464$
5. $464 + 233 = 697$
Verification:
Let's double-check by adding the ones column first:
$2 + 4 + 4 + 4 + 5 + 8 = 27$ (Write down 7, carry over 2)
Next, the tens column:
$1 + 0 + 9 + 5 + 3 + 9 + 2 \text{ (carry)} = 29$ (Write down 9, carry over 2)
Finally, the hundreds column:
$1 + 1 + 0 + 1 + 1 + 0 + 2 \text{ (carry)} = 6$
The total is 697.
Final Answer: 697
