Show Worked Solution

Consider Option B: 15.6 L/min

\(\text{Cardiac output}\)	\(=\text{Heart rate}\times\ \text{Stroke volume}\)
	\(=130\ \text{beats/min}\times 120\ \text{mL/beat}\)
	\(=15\,600\ \text{mL/min}\)
	\(=15.6\ \text{L/min}\)

A is incorrect: Failed to multiply HR and SV
C is incorrect: Decimal conversion error
D is incorrect: Added instead of multiplying values
