Question

On Tuesday Jennifer bought 5 boxes. On Wednesday half of all the boxes were destroyed. On Thursday there were only 20 left? How many boxes did she half on Monday?

Answer 1

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
