I am thinking about proposing taking the 7th grade on a field trip to a chocolate factory.
The total cost for the tour and all the free chocolate they are going to share with us is $750.
The school budget does not provide funds for this field trip, so students will need to pay a fee.
The trip will cost $3 per student IF all 250 students go. However, I know that it is unlikely that all students will go.
Be sure to answer the following in your analysis:
• What kind of relationship between number of students and cost should the teachers expect?
• How can that relationship be expressed with an equation?
What is:
relationship = inverse
equation => cost = 750/#of students

Field trip to chocolate factory cost = $750
After giving it more thought, I decide to just charge $5 per student for the field trip. I will use any extra money to buy extra Dixie cups for the classroom.
How much money will the SCHOOL have to spend on this field trip?
Be sure to answer the following in your analysis:
• What kind of relationship between number of students and cost should the teachers expect?
• How can that relationship be expressed with an equation?
What is:
relationship = linear
equation => cost to school = 750 - 5x
