Question

A grocery store reduced the price of a loaf of bread from $3.20 to $3.12. Find the percent change.

Answer 1

`-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 \%}`
