A store normally sells windows at $100 each. This week the store is offering one free window for each purchase of four. Dave needs seven windows and Doug needs eight windows. How much will they save if they purchase the windows together rather than separately?

    Basically for every five windows, it is 400 dollars.

    So Dave would spend 600 dollars on his windows while the other guy would spend 700

    Add 600 and 700 and then subtract 1200 from that amount.

    600 + 700 = 1300 1300 - 1200 = 100 @SrignanP
