Final answer:
To calculate the target carbon footprint for the next fiscal year, multiply the current carbon footprint by 0.20.
Step-by-step explanation:
To calculate the target carbon footprint for the next fiscal year, we need to determine 20% of the current carbon footprint.
To do this, we can multiply the current carbon footprint (500 metric tons) by 0.20 (which represents 20%).
500 metric tons x 0.20 = 100 metric tons
