A movie ticket for an adult costs $8, and a child's ticket costs $3. One adult is taking a group of children to the movies. She has $35. How many children can she take with her to the movies?
Step-by-step reasoning:
9
Let X be the number of children the adult can take with her.

She has $35, so she could buy one ticket for her and the rest for the children.

So she has $35 - $8 = $27 left for children.

She could take $27 / $3 / child = 9 children with her.

.

Therefore, the answer is 9
