D) 30%

Answer 1

The decreases in employees, park area, and computer price correspond to percentage decreases of 23.53%, 20%, and 20% respectively.

Step-by-step explanation:

To write each decrease as a percent, we calculate the percentage change using the formula: change in quantity divided by the original quantity, and then multiply by 100 to convert it to a percentage. Using the given examples:

• The number of employees decreased from 6800 to 5200. The change is 6800 - 5200 = 1600. Percentage change = (1600 / 6800) * 100 = 23.53%.
• The area of a park decreased from 840 ha to 672 ha. The change is 840 - 672 = 168. Percentage change = (168 / 840) * 100 = 20%.
• The price of a computer decreased from $3000 to $2400. The change is 3000 - 2400 = 600. Percentage change = (600 / 3000) * 100 = 20%.
