You have $25 to spend on snacks for movie night with 4 of your friends. If individuals boxes of raisins are $1.50 and all 5 of you want to buy your own box, find the amount of money that remains per person for popcorn and a drink.
The 5 boxes of raisins will cost a total of 5 x $1.50 = $<<5*1.5=7.50>>7.50.
This leaves $25 - $7.50 = $<<25-7.5=17.50>>17.50 for popcorn and a drink.
Thus, each person will have $17.50 / 5 people = $<<17.5/5=3.50>>3.50 remaining for popcorn and a drink. Answer: \boxed{3.50}.
