So basically i used the trick that 78 has 8 so for the multiplication of 9 there becomes 18 when 9*2=18
Since 8 items are bought. So it is , two musics CDs and 6 Movies
i.e. 9*2 + 10*6 =78

Music CDs cost $9 each, and movies cost $10 each. If you spend $78 and buy 8 items, how many of each did vou buy?
