Final answer:

The percentage change in the price of milk from $1.25 to $2.25 per gallon is calculated to be an 80% increase. You subtract the old price from the new price, divide the difference by the original price, and then multiply by 100 to get the percentage.

Step-by-step explanation:

To calculate the percentage change in the price of milk from $1.25 to $2.25 per gallon, you can follow these steps:

  • Subtract the original price from the new price: $2.25 - $1.25 = $1.00.
  • Divide the increase by the original price: $1.00 / $1.25 = 0.8.
  • Convert the decimal to a percentage by multiplying by 100: 0.8 × 100 = 80%.

Therefore, the percentage change in price is an 80% increase. The correct answer is D) 80 percent.
