Map<invoice__c,List<line_item__c>> myMap = new Map<invoice__c,List<line_item__c>>(); 

/* Populate myMap */ 

List<Invoice__c> invoiceToUpdate = new List<Invoice__c>(); 

for ( Invoice__c inv : myMap.keySet()) { 
    List<line_item__c> lis = myMap.get(inv); 
    Integer sum = 0;
    if (lis != null) {
        for (line_item__c li :lis)
            sum += li.Quantity;
         if (sum > 100) {
              inv.Status = 'newStatus';
               invoiceToUpdate.add(inv);
          }
     }
}

if (invoiceToUpdate.size() > 0)
     update invoiceToUpdate;
}
