Questions: The price of an item has risen to 238 today. Yesterday it was 140. Find the percentage increase.

Solution Steps

We are given:

• The original price of the item: \( \$140 \)
• The new price of the item: \( \$238 \)

The difference in price is calculated as: \[ \text{difference} = \text{new price} - \text{original price} = 238 - 140 = 98 \]

The percentage increase is calculated using the formula: \[ \text{percentage increase} = \left( \frac{\text{difference}}{\text{original price}} \right) \times 100 \] Substituting the values, we get: \[ \text{percentage increase} = \left( \frac{98}{140} \right) \times 100 = 0.7 \times 100 = 70 \]
