Transcript text: The price of an item yesterday was $140. Today, the price rose to $203. Find the percentage increase.
Solution
Solution Steps
To find the percentage increase, we need to calculate the difference between the new price and the old price, then divide that difference by the old price, and finally multiply by 100 to get the percentage.
Step 1: Calculate the Difference
To find the difference in price, we subtract the old price from the new price:
\[
\text{Difference} = \text{New Price} - \text{Old Price} = 203 - 140 = 63
\]
Step 2: Calculate the Percentage Increase
Next, we calculate the percentage increase using the formula:
\[
\text{Percentage Increase} = \left( \frac{\text{Difference}}{\text{Old Price}} \right) \times 100 = \left( \frac{63}{140} \right) \times 100
\]
Calculating this gives:
\[
\text{Percentage Increase} = 45.0
\]
