The price of an oven changes from $450 to $396. (1 point)13.6% increase
13.6% decrease
12% increase
12% decrease
To calculate the percentage change in price, we can use the formula:
Percentage change = ((new price - old price) / old price) * 100%
Using this formula, let's calculate the percentage change in price:
((396 - 450) / 450) * 100% = -11.999999999999996%
Rounding to the nearest whole number, we get -12%.
Therefore, the price of the oven decreased by 12%.
To find the percentage change between two numbers, you can use the formula:
Percentage Change = ((New Value - Old Value) / Old Value) * 100
In this case, the old value of the oven is $450 and the new value is $396.
Using the formula:
Percentage Change = (($396 - $450) / $450) * 100
This simplifies to:
Percentage Change = (-54 / $450) * 100
Calculating the percentage change:
Percentage Change ≈ -12%
Since the percentage change is negative, it indicates a decrease in price. Therefore, the correct answer is a 12% decrease.
