Answers

  1. If Connie spent $26 on 8 books, The number of hard covers she buy is 5 hard cover.

    Number of hardcover bought

    Let h represent hard cover
    Let p represent paperbacks
    Formulate an equation
    h + p= 8…….(1)
    4h + 2p= 26……(2)
    Multiply equation (1) by -2
    -2h + -2p = -16
    4h  +  2p   = 26
    2h  +   0p =10
    2h = 10
    Divide both side by 2h
    h=10/2
    h =5 hard covers
    Paper backs
    P=5-2
    P=3 paper backs
    Therefore If Connie spent $26 on 8 books, The number of hard covers she buy is 5 hard cover.
