Answer:


-2.5\text{ \%}

Step-by-step explanation:

Here, we want to calculate the percentage change in the price of bread

Mathematically, we have it as:


\frac{new\text{ price - old price}}{old\text{ price}}\text{ }*\text{ 100 \%}

From the question:

new price = $3.12

old price = $3.20

Substituting the values, we have it that:


Percentage\text{ change = }(3.12-3.2)/(3.2)\text{ }*\text{ 100 \% = -2.5 \%}
