item	original price	new price	percent change	increase or decrease
scooter	$43	$57	%	(select)
tennis racket	$78	$	5%	increase
skis	$572	$	20%	decrease

74.10 686.40 16 25
33 81.90 457.60 14

Explanation:

Step1: Calculate percent change for bike

Percent change formula is $\frac{\text{New}-\text{Original}}{\text{Original}}\times100\%$. For bike, $\text{Original} = 111$, $\text{New}=96$. So $\frac{96 - 111}{111}\times100\%=\frac{- 15}{111}\times100\%\approx - 14\%$. It's a decrease.

Step2: Calculate percent change for scooter

For scooter, $\text{Original}=43$, $\text{New} = 57$. Then $\frac{57-43}{43}\times100\%=\frac{14}{43}\times100\%\approx33\%$. It's an increase.

Step3: Calculate new - price for tennis racket

If original price of tennis racket is $78$ and percent increase is $5\%$, new price is $78\times(1 + 0.05)=78\times1.05 = 81.90$.

Step4: Calculate new - price for skis

If original price of skis is $572$ and percent decrease is $20\%$, new price is $572\times(1 - 0.2)=572\times0.8 = 457.60$.

Answer:

Bike: 14, Decrease
Scooter: 33, Increase
Tennis Racket: 81.90
Skis: 457.60
