138

Explanation:

The "places" are just the decimal number slots related to their multiplier. A '2' in the 'tens' slot means 2 x 10 = 20. The only trick in this question is the '18 ones'. Of course, in the decimal system each 'slot' cannot exceed 10! That means '10' of the ones have to be moved over to ONE of the 'tens'. That leaves us with 8 left in the 'ones' place.

The final tally is:
'1' in the hundreds place: 100
'2' in the tens place: 20
Another '1' in the tens place from '10' of the 'ones': 10
The remaining '8' in the ones place: 8
All together we have 138.
