if a number decreases from 1,500 to 300 what is the rate of decrease?
80%
8%
50%
62%

Explanation:

Step1: Calculate production change

Production change = 1913 - 1600 = 313 units

Step2: Compute rate of change

Rate = $\frac{313}{1600} \times 100 \approx 19.6\%$

Step3: Calculate number increase

Number increase = 1107 - 900 = 207

Step4: Compute rate of change

Rate = $\frac{207}{900} \times 100 = 23\%$

Step5: Calculate number decrease

Number decrease = 1500 - 300 = 1200

Step6: Compute rate of decrease

Rate = $\frac{1200}{1500} \times 100 = 80\%$

Answer:

19.6%
23%
80%
