QUESTION 5 Solve. 10 points The price of a printer was reduced from \( \$ 400 \) to \( \$ 300 \). What was the percent of decrease? \( 25 \% \) \( 75 \% \) \( 30 \% \) \( 33.3 \% \)

Step 1 ：\( \text{Decrease} = \$ 400 - \$ 300 = \$ 100 \)

Step 2 ：\( \text{Percent of decrease} = \frac{\text{Decrease}}{\text{Original price}} \times 100 \%

Step 3 ：\( \text{Percent of decrease} = \frac{\$ 100}{\$ 400} \times 100 \% = 25 \% \)
