Hi there!
First, you will need to multiply the amount of movies times the base price.
5 * 2 = 10
Now, 25% is a quarter and we know a quarter of 10 is 2.5.
This means that the normal price with no deal will be $10.
Subtract $2.50 and you have your answer!
10 - 2.5 = 7.5
He only has to pay $7.50 and saves $2.50!
