a colection of stamps consist of 2 cent stamps, 8 cent stamps, and 14 cent stamps. The number of 2 cent stamps is five more then twice the number of 8 cent stamps.the number of 14 cent stamps is three times the number of 8 cent stamps. The total value of the stamps is $2.26. Find the number of each type of stamp in the collection.

  • Algebra - ,

    Letting x, y, and z equal the numbers of .02, .08 and .14 cent stamps.

    1-x = 2y + 5
    2-z = 3y
    3-.02x + .o8y + .14z = 2.26
    4-Times 100 yields 2x + 8y + 14z = 226
    5-Substituting (1) and (2) into (4) yields
    ..2(y + 5) + 8y + 14(3y)
    6-Can you take it from here?
