Answer:
This is a percent INCREASE
The percent change is 83.33%
Step-by-step explanation:
Let us solve the question
∵ A pair of Jordans sold at retail for $180
∴ The initial price = 180
∵ Now it sells for $330 aftermarket
∴ The new price = 330
→ That means the new price is greater than the initial price
∵ The new price is greater than the initial price
∴ This is a percent INCREASE
∵ The percent of change = (amount of increase ÷ initial amount) × 100%
∵ The amount of increase = new price - initial price
∴ The amount of increase = 330 - 180 = 150
→ Substitute it in the rule of percent of increase above
∵ The percent change = × 100%
∴ The percent change = × 100%
∴ The percent change = 83.33%
