1 answer

To find the percent of increase or decrease, we can use the formula:

Percent Change = ((New Price - Old Price) / Old Price) x 100

Plugging in the values:

Percent Change = (($306.46 - $398) / $398) x 100
Percent Change = (-$91.54 / $398) x 100
Percent Change = -0.22975 x 100
Percent Change = -22.975%

Therefore, the percent decrease is 23%, which means the correct answer is:

d. 23% decrease
