Rolled throughput yield multiplies the exact serial step yields.

highlighted = computed this step

RTY Product

Rolled throughput yield is the serial product of the step yields.

RTY=yield A×yield B×yield C\text{RTY} = \text{yield A}\times\text{yield B}\times\text{yield C}

Final RTY

RTY is 3/5 and final good units are 120.
