Final answer:
To calculate the percentage change, subtract the old value from the new value, divide by the old value, and multiply by 100.
Step-by-step explanation:
To calculate the percentage change in banana consumption from 2017 to 2018, you can use the formula:
Percentage change = [(new value - old value) / old value] x 100
First, subtract the old value (30,000) from the new value (35,000) to get 5,000. Then, divide 5,000 by the old value (30,000) to get 0.1667.
Multiply by 100 to get the percentage: 16.67%. Therefore, the percentage change in banana consumption is 16.67%
