at the beginning of the year the price of a gallon of milk was $3.00. now it costs $3.90. what is the percent change? ?%
Answer
Explanation:
Step1: Find the amount of change
$3.90 - 3.00=0.90$
Step2: Use the percent - change formula
Percent change=$\frac{\text{Amount of change}}{\text{Original amount}}\times100%$ Substitute the values: $\frac{0.90}{3.00}\times100%$
Step3: Calculate the result
$\frac{0.90}{3.00}=0.3$, and $0.3\times100% = 30%$
Answer:
30%
