Question

UpStudy AI · Accepted Answer

To determine the **rate of decrease** when a number changes from 1500 to 300, you can use the formula for **percentage decrease**:

$$
\text{Percentage Decrease} = \left( \frac{\text{Initial Value} - \text{Final Value}}{\text{Initial Value}} \right) \times 100\%
$$

Plugging in the values:

$$
\text{Percentage Decrease} = \left( \frac{1500 - 300}{1500} \right) \times 100\% = \left( \frac{1200}{1500} \right) \times 100\% = 0.8 \times 100\% = 80\%
$$

**So, the number decreased by 80%.**
The number decreased by 80%.
