To do these, always convert the percents to decimals, so you can subtract it from 1. Remember, 1 is the whole. When you subtract the part that's taken off, you are left with what you have to pay. If you have 20% off of $100, then you are paying for 80% of $100. of means to multiply so you would multiply: 0.8X100, which would be $80.
First, multiply 125x0.8
Multiply that answer by 0.7
You should get B. $70

multiple 22.90x0.93

You should get D

After applying a 20% discount followed by an additional 30% discount on a product priced at $125, the final price is $70 (Option B). For the DVD that costs $22.90 including a 7% sales tax, the price before tax is approximately $21.40 (Option A).
