postnew [5]

Hello there! Your answer would be: each persons share was $4.46.

Okay, so to solve this divide the total amount by the number of people there. Note that the equation says "Nina and 3 friends" indicating that Nina is one of these people, and there are 3 others, so we have 4 in total.  

$17.84 ÷ 4 = $4.46

So, each person paid $4.46. I hope this helped, and have a great rest of your day! :)
