Answer:
She had had 29 boxes on Monday.
Step-by-step explanation:
Let m
represent the number of boxes Jennifer had on Monday.
She bought 5 boxes on Tuesday which would bring the number of hats she had to m + 5
Half of her boxes were destroyed on Wednesday, so on Thursday she would have m
+
5/2 boxes
We are told this number equals 17
so
m+5/2 = 17
m + 5 = 34
m = 29
