    Part A y = 5x + 120 Part B 320 dollars.

    Step-by-step explanation:

    y = 5x + 120

    The slope represents the cost per person.

    Let x = 40 people.

    y = 5x + 120 y = 5*40 + 120 y = 200 + 120 y = 320

    The cost of a party of 40 people would be 320 dollars

    5x + 120 = y

    40 = x

    5 (40) + 120 = y

    200 + 120 = y

    320 = y

    So the total cost is $320

    The linear equation is

    y = 5x + 120
