Question

You are baking cookies for your class. There are 23 total students in your class and you have baked 12 cookies. Write and solve an equation to find the additional number x of cookies you need to bake in order to have 2 cookies for each student. Write your equation so that the units on each side of the equation are cookies per student.

Basically I have already tried a bunch of different ways of writing this but they all didn't work out.

Answer 1

34 because multiply 23 by 2 then subtract 12 and you get 34

Answer 2

(23 x 2) - 12 = x

We need 2 cookies per student, so multiply the amount of students by 2. which is 23 x 2. Then because you already baked 12 subtract 12 from the original amount you needed to bake. Which is 46 - 12. Oh and if you wanted the answer, it's 34.
