The two cereal boxes shown have corresponding edges in a ratio of 2:3. If the smaller box sells for $2.50 and the larger box for $4.00, which is the better buy? Why? What assumption(s) do you have to make when solving the problem? Estimate, then check.

Could someone show me how to solve this? I don't know what formulas to use.

  • Math -

    what is 1/2 - 1/2
    Im doing modeling subtraction of fractions

  • Math -

    The volumes of the two similar boxes are proportional to the cubes of their corresponding sides.

    so the larger box:smaller box = 27:8

    so the larger holds over 3 times as much as the smaller.
    Now look at the cost.
