Answer:
Step-by-step explanation:
The increase is 12.50 -10.00 = 2.5
As a proportion of the original cost this is 2.5/10 = 0.25.
Multiply through by 100 to give this as a percentage.
In other words, it is a 25% increase.
(To be clear, this is the increase in the price of the movie ticket. Your question for some reason talks about a television increase).
