Rn u wanna focus on these  parts "he tickets cost $1,250" and "bringing the total cost to $1,400"

You wanna (Subtract) (1,250.00) from (1,400.00)

$$1,400.00-1,250.00=150$$

Divide (150) by (1,250.00)

$$150\div1,250.00=0.12$$

To make (0.12) a percentage u wanna (Multiply) it by (100)

$$0.12\times100=12%$$

So with all this being said Answer option A would be correct
