Textbook Problem

Solve the following problem for the rate of increase or decrease. Round to the nearest tenth of a percent when necessary.

If a number decreases from 21 to 15, what is the rate of decrease?

To determine

**To calculate:** The rate of decrease if it is given that the number decreases from

Explanation

**Given Information:**

The number decreases from

**Formula used:**

Follow the steps mentioned below to determine the rate of increase or decrease:

Step1: Find the original and the new values and then calculate the difference between them.

Step2: Use the rate formula

Step3: Calculate the value of Rate, the value of Rate will be in decimal form. So, convert it into percent form.

**Calculation:**

The number changes from

Consider that the original value or the base is

Now calculate the difference between original value and the new value to determine the value of portion
