Final answer:
To ensure each of the 23 students gets 2 cookies, you need to bake an additional 34 cookies.
Step-by-step explanation:
To find out how many additional cookies you need to bake to have 2 cookies for each of the 23 students in your class, you can set up the following equation:
Let x be the additional number of cookies you need to bake. Since you have already baked 12 cookies, the equation to represent the total cookies needed is:
Current cookies + additional cookies = total cookies needed
12 + x = 2 × 23
The total number of cookies needed is twice the number of students because each student needs 2 cookies:
12 + x = 46
To solve for x, subtract 12 from both sides of the equation:
x = 46 - 12
x = 34
Therefore, you need to bake an additional 34 cookies.
