A class of 30 high school students is preparing for a field trip. If each student contributes $2 every Friday for their trip, how many dollars will they have in 2 months? Give me reasons, before answering the question
They save 30 students * $2 / student / week = $60 / week. They saved for 2 months which is 2 months * 4 weeks / month = 8 weeks. So in 2 months, they will have $60 / week * 8 weeks = $480. So the final answer is 480.
