Answer:
10.4%
Step-by-step explanation:
The original price = $2.40
Price after drop = $2.15
The drop = $2.40 - $2.15 = $0.25
Percentage decrease = [tex]\frac{decrease}{original-price}[/tex] × 100
i.e Percentage decrease = [tex]\frac{0.25}{2.40}[/tex] × 100 = 10.41666667%
Or 10.4% (Rounded up to nearest tenth of a percent).
