Answer
The percentage decrease is 3.49%
Explanation:
According to the data given:
The initial data for chef/head cooks = 100,400
It is expected to decrease to 96,900 by 2020
Percentage decrease in chefs and head cooks can be calculated as follows
Percentage change = new - old / old * 100%
Percentage change = 96,900 - 100,400 / 100, 400 * 100%
Percentage change = -3500 / 100400 *100%
Percentage change = -0.0349 * 100%
Percentage change = -3.49%
Hence, the percentage decrease in chefs and head cooks is 3.49%
