Shane and Kate are preparing to go on long car trips with their families. Shane bought 8 books and 2 CDs for $73.60. Kate bought 3 books and 4 CDs for $69.85. Both totals were withour tax. All of the books were the same price and all of the CDs cost the same. How much did a book cost?

    8B+2C=73.60
    3B+4C=69.95


    I would multiply the first equation by 2, then subtract equation 2 from the new 1.
