Answer:

11175

Step-by-step explanation:

Person 1 will shake hands with 149 others
Person 2 ... 148 (excluding the first person)
Person 2 ... 147 (excluding the first two persons)
...
Person 149 ... 1 (with person 150)
Person 150 ... none (already had 149 handshakes)

Total handshakes:

1 + 2 + ... 149 = 149(1 + 149)/2 = 11175
