Answer:
B.8%
Explanation:
First, you figure out that the price increased by ten cents by subtracting the old price from the new one.
Then you figure out what one percent of 1.25 is by dividing it by 100 to get 0.0125.
Finally you can plug in each answer and multiply it with 0.0125 so you end up with 10 cents or 0.1.
8 is the correct answer.
