Question

Mrs. Ashe is planning to take her study group on a field trip to an amusement park. The regular cost is $7.00 per person. There is a party special that costs $4.00 per person with an additional $30.00 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.

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. (50 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. (50 points)

    Hey there!

    a) Your answer is y = 7x.

    When we are making this equation, we need to find the values for m and b and plug those into y = mx + b.

    The regular cost is $7 per person. This is the value for m, since x is the amount of people.

    There is no additional cost, so b = 0.

    Plugging those values in, we have y = 7x.

    b) Your answer is y = 4x + 30.

    Let’s find the values for m and b again.

    Since the party special costs $4 per person, m is equal to 4.

    There is an additional $30 fee, which is the value for b because this fee will be there regardless of the amount of people.

    Plugging those values in, we have y = 4x + 30.

    Again, here are the answers:

    a) y = 7x

    b) y = 4x + 30

    Hope this helps!
