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!!

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. 
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
