A) 12.5%
B) 10%
C) 13.33%
D) 11.11%

Answer 1

The percent decrease is 12.5%.

Step-by-step explanation:

To calculate the percent decrease, we can use the formula:

Percent Decrease = (Initial Value - Final Value) / Initial Value * 100

In this case, the initial value is 1600 and the final value is 1400. Plugging these values into the formula, we get:

Percent Decrease = (1600 - 1400) / 1600 * 100 = 200 / 1600 * 100 = 0.125 * 100 = 12.5%

Therefore, the percent decrease is 12.5%, which corresponds to option A.
