    Out of them, the mantle is the thickest layer, while the crust is the thinnest layer. The Earth can be divided into four main layers: the solid crust on the outside, the mantle, the outer core and the inner core.

  2. Answer:

    Let the cost of red tube be $ x

    cost of blue tube= $ x + 7

    in equation

    x+x+7=$25

    2x+7=$25

    2x=$25-7

    2x=$18

    x=$18/2

    x=$9

    hence the cost of red tube is, $9

    the cost of blue tube is,$9+$7=$16
