Final answer:
The percentage decrease from 2500 to 1400 is calculated by dividing the amount of decrease (1100) by the initial amount (2500), then multiplying by 100, resulting in a 44% decrease.
Step-by-step explanation:
To calculate the percentage decrease from 2500 to 1400, you subtract the final value from the initial value and divide that by the initial value. Then you multiply by 100 to get the percentage.
Here's the formula and calculation:
Percentage Decrease = ((Initial Value - Final Value) ÷ Initial Value) x 100
Percentage Decrease = ((2500 - 1400) ÷ 2500) x 100
Percentage Decrease = (1100 ÷ 2500) x 100
Percentage Decrease = 0.44 x 100
Percentage Decrease = 44%
Therefore, the percentage decrease is 44%, which corresponds to option c.
