The price of a notebook was $3.65 yesterday. Today the price fell to $3.40. Find the percentage decrease.

6.85% decrease

Step-by-step explanation:

Initial Price = $3.65

Final Price = $3.40

Difference in price = Final - Initial = $3.40 - $3.65 = - $0.25

The negative sign indicates that the price decreased hence we can say that the decrease is positive $0.25.

% decrease

= (Amount decreased / initial price) x 100%

= (0.25 / 3.65) x 100%

= 6.85% decrease
