Question

The cost in dollars of a class party is 59+13n, where n is the number of people attending. What is the cost of 44 people?

Answer 1

The function is:

C(n) = 59 + 13n

where n is the number of people, and C(n) is the cost of a class party.

To determine the value of C(n) where n = 44, just replace this value of n into the previous formula, and simplify the expression, just as folow:

C(44) = 59 + 13(44)

C(44) = 59 + 572

C(44) = 631

Hence, the cost for 44 people is 631 dollars.
