write an expression that illustrates the total cost of all baked goods in this scenario using the variable s to represent the cost of scones& the variable c to represent the cost of cookies simplify expression by combining like terms.
You bake two baking sheets with 12 scones, each two baking sheets with 20 cookies each & one baking sheet with 2 scones & 10 cookies.
Thanks!!

  • Math - ,

    2 sheets x 12 s
    2 sheets x 20 c
    1 sheetx (2s+10c)
    =================
    (2x12s) + (2x20c) + (1 x (2s+10c) =
    24s + 40c + 2s + 10c =
    26s + 50c = total cost of scones + cookies.

  • Math - ,

    S is the cost of scones
    c is the cost of cookies
    x is the cost of baking sheets

    so the equation becomes 2x + 12 = s
    2x + 20 = c
    similarly,
    x + 2 = s
    x + 10 = c
