Question: 1 / 400

If a store increases a product's price from $50 to $70, what is the percentage increase?

30%

40%

To find the percentage increase in the product's price, you start by determining the amount of the increase. The initial price is $50 and the new price is $70. The increase in price is calculated as follows:

Increase = New Price - Original Price

Increase = $70 - $50

Increase = $20

Next, to find the percentage increase, you divide the increase by the original price and then multiply by 100 to convert it into a percentage:

Percentage Increase = (Increase / Original Price) × 100

Percentage Increase = ($20 / $50) × 100

Percentage Increase = 0.4 × 100

Percentage Increase = 40%

Thus, the correct percentage increase when the product's price rises from $50 to $70 is 40%.
