Justify your answer using equations, models, and/or words to explain your mathematical reasoning. i need a model and answer. Thx. Will Medal!

Answer 1

"20% off regular price" can be calculated by multiplying the regular price by (1.00-0.20), or 0.80.  Thus, the discounted price will be 0.80($120), or $96.
