Multi-row wouldn't generate the output format in your example, since you're looking to generate 3 new rows. The best you can achieve with a multi-row would be a new column with a running total for each type. There is also a Running Total tool that can do this, but it is essentially a group and sum action like the summarize tool, so you might as well use summarize.
