Question

Which describes the calculations that could be used to solve this problem? Lauren has 42 muffins to pack into boxes and bags. She has one box that will hold 12 muffins. She will put the rest of the muffins into bags. She wants to put 3 muffins into each bag. How many bags of muffins will Lauren be able to make? A. Subtract 42 – 12. Then multiply the difference by 3. B. Add 3 + 12. Then add 42 to the sum. C. Add 42 + 12. Then divide the sum by 3. D. Subtract 42 – 12. Then divide the difference by 3

Answer 1

The correct answer is D, 'Subtract 42 - 12. Then divide the difference by 3'. Lauren has 42 muffins, and she can put 12 of them into a box, leaving her with 30 muffins to fit into bags. If she can fit 3 muffins in each bag, and she wants to know how many bags she needs, then she needs to divide 30 by 3 to get 10. This means that she will need 10 bags of 3 muffins to completely pack 30 muffins. She started with 42, but 12 of those fit into the original box, so we don't have to worry about it.

Hope this helps!
