Answer:
Therefore, Jeff had $22 at the beginning of the day.
Explanation:
Amount of money that Jeff had at the end of the day = $110
But it is given that : Jeff had a lemonade stand and ended up with 5 times as much money at the end of the day than at the beginning.
Now, We need to find the amount of money that Jeff had at the beginning.
Let the amount that Jeff had at the beginning of the day be $x
So, According to the condition given in the problem,
⇒ 5 × x = 110
⇒ 5x = 110

Therefore, Jeff had $22 at the beginning of the day.
