a) 250%
b) 40%
c) 60%
d) 166.5%

Answer 1

The percent change from 250 to 150 is a 40% decrease. You calculate this by dividing the change in quantity (-100) by the original quantity (250) and then multiplying by 100 to get a percentage.

Step-by-step explanation:

To find the percent change from 250 to 150, you can use the formula:

Percentage change = (Change in quantity / Original quantity) × 100%

First, calculate the change in quantity:

Change in quantity = New value - Original value = 150 - 250 = -100

Next, divide this by the original quantity:

-100 / 250 = -0.40

Finally, convert this to a percent:

-0.40 × 100% = -40%

The minus sign indicates a decrease. Therefore, there has been a 40% decrease from 250 to 150, which corresponds to option b.
