Big ! (p-.20 p=new price.) "natasha bought a racket that was marked down 20%" (my equation was in first parenthesis) if the racket was originally priced at $125, how much did natasha pay? what does 0.8p represent in the situation?

The number of calories you burn depends on your weight. a 110-pound person burns 163 calories during 30 minutes of tennis. find the number of calories that a 190-pound person would burn during the same activity, assuming they burn calories at the same rate.
