Ralph and Sandra baked cookies. They gave half of all their cookies to their classmates. Then they gave half of what was left to their teachers. They then ate the remaining 12 cookies. How many had they made all together?
The total amount of cookies that were made was 48.
If they give half of the cookies (48 cookies total) to the class, the give half of what is left (24 is left), and they eat 12, the the answer is 48 cookies total.
