Answer

Explanation:

Step1: Calculate percentage - change formula

The formula for percentage change is $\text{Percentage Change}=\frac{\text{New Value}-\text{Old Value}}{\text{Old Value}}\times100%$. If the result is positive, it is a percentage increase. If negative, it is a percentage decrease.

Step2: Doll - price calculation

For the doll, old value $=$29$, new value $=$23$. $\text{Percentage Change}=\frac{23 - 29}{29}\times100%=\frac{- 6}{29}\times100%\approx - 21%$, so it is a 21% decrease.

Step3: Milk - price calculation

For milk, old value $=$3.09$, new value $=$2.16$. $\text{Percentage Change}=\frac{2.16 - 3.09}{3.09}\times100%=\frac{-0.93}{3.09}\times100%\approx - 30%$, so it is a 30% decrease.

Step4: Concert - ticket calculation

For the concert ticket, old value $=$76$, new value $=$99$. $\text{Percentage Change}=\frac{99 - 76}{76}\times100%=\frac{23}{76}\times100%\approx30%$, so it is a 30% increase.

Step5: Hotel - room calculation

For the hotel room, old value $=$125$, new value $=$145$. $\text{Percentage Change}=\frac{145 - 125}{125}\times100%=\frac{20}{125}\times100% = 16%$, so it is a 16% increase.
