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 = × 100 = 7.2% (rounded up to the nearest tenth of a percent)
