Question

Nick has 800 candy bars to sell for a fundraiser. Let C be the number of candy bars. Let P be the amount made from selling the candy bars. Suppose that P equals 3 C minus 400 gives P as a function of C. Identify the correct description and appropriate set of values for the domain of the function.

Answer 1

The domain of the function P = 3C - 400, where C is the number of candy bars, is the set of all non-negative whole numbers.

Step-by-step explanation:

The given function that represents the amount made from selling candy bars is P = 3C - 400, where C is the number of candy bars. To find the correct description and domain of the function, we need to consider the possible values of C for which the function is defined.

Since C represents the number of candy bars, it cannot be negative or fractional. The domain of the function is therefore the set of all non-negative whole numbers:

Domain: {0, 1, 2, 3, ...}
