The price of a notebook was $3.45 yesterday. Today, the price rose to $3.95. Find the percentage increase. Round your answer to the nearest tenth of a percent.

Answer 1

Initial Value: $3.45

Final Value: $3.95

The price of a notebook increased by $0.50.

Divide $0.50 by the initial value, $3.45, and multiply by 100.

$0.50/$3.45 = 0.1449 × 100 = 14.49% ≈ 14.5%

The price of a notebook increased by 14.5%.
