Answer: 44 hours

Explanation:

Setting up a simple equation will help us solve this (x represents Mary's hours):


x + (x - 8) = Total Hours

We know this because we know that Jessica works 8 hours less than Mary, which we find by subtracting 8 from Mary's hours.

We then need to plug in Mary's hours:


26 + (26 - 8) = 26 + 18 = 44

Hope this helped, if you need anything else explained please let me know.
