The Problem:

Mrs. Ashe is planning to take her study group on a field trip to an amusement park. The regular cost is $55 per person. There is a party special that costs $46 per person with an additional $45 fee for a private room where students can eat lunch. Mrs. Ashe is trying to decide if she should use the regular price or the party special.

Part 1:

A) Write an equation in slope-intercept form (y=mx+b) to show the total cost of the regular price with x people, where x = number of students in the study group and y = the total cost.



B) Write an equation in slope-intercept form (y=mx+b) to show the total cost of the party special with x people, where x = number of students in the study group and y = the total cost.
