Question

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

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

Answer 1

I assume s is the cost of one scone, and c = cost of one cookie.

Otherwise, B, the total baked goods cost = s+c

Let S = cost of scones = s * number of scones
= s * (2*12 + 1*2)

Let C = cost of cookies = c * number of cookies
= c * (2*20 + 1*10)

S = 26s
C = 50c

B = S+C = 26s + 50c
