Daniel needs to bake cookies for a bake sale. Each cookie will cost dollars. Brandon makes 12 chocolate chip cookies and 18 sugar cookies. Create an expression that represents Taylor's total cost of the cupcakes.

An expression that represents Taylor's total cost of the cupcakes is written as:

y = 30x

Step-by-step explanation:

We are told in the question:

Brandon makes 12 chocolate chip cookies and 18 sugar cookies.

Let us represent the total cost of cookies as y

The price of each cookies as x

Therefore,an expression that represents Taylor's total cost of the cupcakes is written as:

y = 12x + 18x

y = 30x

x = 3 ± √(5+y)
