Algebraic expression for total cost of all baked goods

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 cookes. Write an algebraic expression that illustrates the total cost of all baked goods 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.

Re: Algebraic expression

number of scones =2x12+2
# scones=26
cost of a scone=s

number of cookies= 2x20+10
# cookies=50
cost of a cookie=c

total cost= cost of scones + cost of cookies
total cost = 26s+50c answer

you should do it by writing one expressioin for total cost and then reducing it to the above answer
