Explanation
We are required to determine how much each person paid.
To do so, we will use the formula
[tex]\frac{Total\text{ amount spent}}{total\text{ number of people}}[/tex]We are told that Jason and his three friends went out to eat.
That means that there are 4 people including Jason
They all spent 17.40
So we can find the amount each spent using the formula above
[tex]amount\text{ each person spent=}\frac{17.40}{4}=4.35[/tex]Therefore, each person paid 4.35
