QUESTION 4 Solve. The price of a printer was reduced from \( \$ 400 \) to \( \$ 300 \). What was the percent of decrease? \( 75 \% \) \( 33.3 \% \) \( 25 \% \) \( 30 \% \)

Step 1 ：\( \text{Decrease} = \text{Original Price} - \text{Reduced Price} = 400 - 300 \)

Step 2 ：\( \text{Decrease} = 100 \)

Step 3 ：\( \text{Percent of Decrease} = \frac{\text{Decrease}}{\text{Original Price}} \times 100\% = \frac{100}{400} \times 100\% \)

Step 4 ：\( \text{Percent of Decrease} = 25\% \)
