A school is planning a community outreach program. Each classroom must raise $200 for this activity. Classroom A has raised $20 from each of two families, $10 from each of eight families, and $5 from each of ten families. How much more money does Classroom A need in order to reach the goal? Give me reasons, before answering the question

Classroom A raised 2 x $20 = $40 from two families. They raised 8 x $10 = $80 from eight families. They raised 10 x $5 = $50 from ten families. Altogether, they raised $40 + $80 + $50 = $170. Therefore, they need $200 - $170 = $30 more to reach the goal. So the final answer is 30.
