Question

maria bought seven boxes. a week later haft of all her boxes were destroyed in a fire. there are now only 22 boxes left. withh how many did she start

Answer 1

We will work backward to find the boxes she started with.

She had 22 in the end.

Half of the boxes were destroyed in a fire, put back the half of the boxes:

22 + 22 = 44

She bought 7 boxes, take away the 7 boxes:

44 - 7 = 37

Answer: She had 37 when she started.
