The Problem:
Mrs. Ashe is planning to take her study group on a field trip to an amusement park. The regular cost is $50 per person. There is a party
special that costs $35 per person with an additional $300 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. (10 points)
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. (10 points)

The slope (m) in each of the slope-intercept equations is the "unit rate" or cost per person. The intercept (b) is any additional cost that does not depend on the number of persons.

__

A) The cost is $50 per person with no additional costs:

y = 50x

__

B) The cost is $35 per person with an addition fee of $300:

y = 35x +300
