    Corrected Question

    I am donating packages for Christmas drive. After the first week, I spent 126 to donate three children packages and 8 adult packages. After two weeks I spent 108 to donate six children packages and 4 adult packages. What is the price of each type of package

    Answer:

    Adult package costs $12

    Child's package costs $10.

    Step-by-step explanation:

    Let the cost of a child's package = c

    Let the cost of an adult package = a

    First Purchase

    Cost of three children packages and 8 adult package=$126

    3c+8a=126

    Second purchase

    Cost of six children packages and 4 adult packages=$108

    6c+4a=108

    Multiply this equation by 2 to make the coefficient of a the same as the other equation

    12c+8a=216

    We solve the two resulting equations simultaneously

    3c+8a=126 12c+8a=216

    Subtract

    -9c=-90

    Divide both sides by - 9

    c=10

    Substitute c=10 into 3c+8a=126 to solve for a

    3 (10) + 8a=126

    8a=126-30

    8a=96

    Divide both sides by 8

    a=12

    Therefore, an adult package costs $12 while a child's package costs $10.
