A phone you bought last week for $300 is now on sale for $225.  Find the percent decrease

To calculate the percent decrease, you can use the formula:

\[
\text{Percent Decrease} = \left( \frac{\text{Original Price} - \text{New Price}}{\text{Original Price}} \right) \times 100
\]

### Step 1: Subtract the new price from the original price.
\[
300 - 225 = 75
\]

### Step 2: Divide the difference by the original price.
\[
\frac{75}{300} = 0.25
\]

### Step 3: Multiply by 100 to get the percentage.
\[
0.25 \times 100 = 25\%
\]

So, the percent decrease is **25%**.
