How do I perform mathematical update from fields using select statement

I would like be able to update multiple fields with a mathematical function. For example in this example query I would like each field to be 76% of the original fields value.

select CHARGE from SHCOSTS where COST_CODE='R'and L_WEIGHT < 5.001

set CHARGE = CHARGE *0.76
where COST_CODE='R'and L_WEIGHT < 5.001
