Dad baked a batch of cookies. My brother ate half my mom ate a fourth of the batch. Dad ate 3 and I ate the last two. How many cookie did dad bake? PLEASE help me figure this problem out?
after mom and brother got done, there was 1/4 batch left.
The last 1/4 batch was 5 cookies, so the whole batch was 20.
0.5x + 0.25x + 5 = X
0.75X + 5 = X
5 = X - 0.75X
5 = 0.25X
5/0.25 = X
20 = X
Thank you!
To figure out how many cookies your dad baked, let's break down the problem step by step.
1. Your brother ate half of the batch: This means that half of the batch of cookies is gone. So, we now have half of the original batch remaining.
2. Your mom ate a fourth of the batch: This means that she ate 1/4 of the remaining batch. Since we know there is half of the original batch left, we need to find 1/4 of that.
3. Dad ate 3 cookies: Now, we subtract the 3 cookies your dad ate from the remaining cookies.
4. Finally, you ate the last two cookies: This means there are no more cookies left.
Let's put this information together to find out the original number of cookies your dad baked:
1. We know that half of the batch is left after your brother ate. This means there were twice as many cookies as the remaining half.
2. Then, your mom ate a fourth of the batch. So, you can multiply the remaining half by 4 to get the original size of the batch.
3. Subtract the 3 cookies your dad ate from the total.
4. Then subtract the 2 cookies you ate from the remaining number.
By going through these steps, we can find the original number of cookies your dad baked.
