If I let c = the number of calendars she usually buys, and p = the dollar value of the standard price of one calendar, I can say that (1.5c) (0.8p) is her total cost at the discounted price.I get (1.5c) (0.8p) = 1.2cp. 120 times the standard price of one calendar is 120p.


Now what should I do after this.

Please help and advise.

Thanks ,
