3. In your industrial oven, you bake two baking sheets with 12 scones each, two baking sheets with 20 cookies each, and one baking sheet with 2 scones and 10 cookies.
a. Write an expression that illustrates the total cost of all baked goods in the scenario above using the variable s to represent the cost of scones, and the variable c to represent the cost of cookies. Simplify your expression by combining like terms.
Please help me with this. I have 12(2)+2=S and 20(2)+10=C. The assignment implies to me that I should write one expression not two, also I wrote equations, and this does not represent the cost of the cookies and scones. What am I overlooking? The assignment is due today.
Got help on this..... Thanks to Reiny who helped another student with the same problem.
