Answer:

7.2% increase (rounded up to the nearest tenth of a percent)

Step-by-step explanation:

The price of the notebook today is $3.70

The price of the same notebook (original price) yesterday was $3.45

Increase in price = $3.70 - $3.45 = $0.25

Percentage increase = (Increase ÷ original price) × 100

Percentage increase = [tex]\frac{0.25}{3.45}[/tex] × 100 = 7.2% (rounded up to the nearest tenth of a percent)
