Calculating the Change in Apple Prices

To calculate the change in the price of apples over two months, we can use the percentage change formula. First, we'll calculate the increase in December and then the decrease in January.

Step 1: Calculate the Increase in December The price of apples increased by 20% in December.

Step 2: Calculate the Decrease in January The price of apples decreased by 14% in January.

Calculating the Overall Change

To calculate the overall change in the price of apples over the two months, we can use the formula for percentage change.

Percentage Change Formula: \[ \text{Percentage Change} = \frac{\text{New Value} - \text{Old Value}}{\text{Old Value}} \times 100\% \]

Step 3: Calculate the Overall Change Using the percentage change formula, we can calculate the overall change in the price of apples over the two months.

\[ \text{Overall Change} = \frac{-14 - 20}{20} \times 100\% \]

\[ \text{Overall Change} = \frac{-34}{20} \times 100\% \]

\[ \text{Overall Change} = -1.7 \times 100\% \]

The overall change in the price of apples over the two months is a decrease of 1.7%.
