Answer:
percent increase = 25%
Step-by-step explanation:
The price of a gallon of milk has increased from $3.24 to $4.05
LEt x be the percentage increase
intitial cost + initial cost times percentage = new cost
[tex]3.24 + 3.24 (\frac{x}{100})= 4.05[/tex]
Subtract 3.24 from both sides
[tex]3.24 (\frac{x}{100})= 0.81[/tex]
divide by 3.24 on both sides
[tex](\frac{x}{100})= 0.25[/tex]
Multiply both sides by 100
x= 25 %
