Question 13332: Anne has some number of cookies which she wants to distribute to kids in the room. If she gives each kid 9 cookies, 1 cookies will be left in her hand 9n+%2B+1+=+C. If she tries to give each kid 10 cookies, she will need more 13 cookies than she has now 10n+=+c+%2B+13. How many kids are there in the room?

First of all, you need to set up equations to fit the problem. I have added these to your question. I have used C as the number of cookies, and n as the number of students in the room. Now that you know the equations, you can substitute 9n+1 for C in the second equation to get 10n+=+%289n+%2B+1%29+%2B+13. To solve, first add like terms to get 10n+=+9n+%2B+14. Then, move 9n over to get 1n+=+14. There are 14 kids in the class.
