SOLUTION

11 15 15/x

Jonah spent the cost of a movie ticket and split the cost of popcorn, so this needs to be represented by a " + ". Jonah just buy one piece tickets, so 11 is tickets price. We know Jonah's costs represented by the expression 11+15/x, "x" on behalf of the number of he and his friends, so 15 is the price of popcprn. 15/x means one person's money for the poopcorn, including Jonah.
