Yesterday = $3.60
Today =     $3.10

% Decrease =      ((3.60 - 3.10) / 3.60)  * 100%
   
                     =   (0.50/3.60)   * 100%
 
                     ≈       0.1389* 100%
  
                     ≈ 13.89 %

                    ≈ 13.9 %   to the nearest tenth.

Answer:

-13.9 %

Step-by-step explanation:

Given,

The price of notebook yesterday or original price = $ 3.60,

Today, the price of the notebook or new price = $ 3.10,

Hence, the percentage decrease = [tex]\frac{\text{New price - Original price}}{\text{Original price}}\times 100[/tex]

[tex]=\frac{3.10-3.60}{3.60}\times 100[/tex]

[tex]=-\frac{50}{3.60}[/tex]

[tex]=-13.8889\%[/tex]

[tex]\approx -13.9\%[/tex]
