Find two items that have changed in price. Record the old and new price. Compute the % change.

The price of coffee increased by 30%, and the price of eggs increased by 20%. We used the formula for percent change to calculate these values. This method can be applied to any items with price changes to find the percentage increase or decrease.

Sure! Here's an example of how to find two items with price changes and compute the percent change:

Item 1: Milk (1 gallon)
Old Price: $3.50
New Price: $4.00
% Change Formula:
\text{Percent Change} = \left( \frac{\text{New Price} - \text{Old Price}}{\text{Old Price}} \right) \times 100
= \left( \frac{4.00 - 3.50}{3.50} \right) \times 100 = \left( \frac{0.50}{3.50} \right) \times 100 \approx 14.29%
→ Price increased by ~14.29%

Item 2: Bread (loaf)
Old Price: $2.80
New Price: $2.24
= \left( \frac{2.24 - 2.80}{2.80} \right) \times 100 = \left( \frac{-0.56}{2.80} \right) \times 100 = -20%
→ Price decreased by 20%

Would you like help finding current prices of specific products (e.g., groceries, electronics) from real stores? I can do that if you let me know the item or store. ;
