Question 1193104: Donna is a software saleswoman. Let P be Donna’s total pay (in dollars). Let N be the number of copies of English is fun she sold. Donna has 140 copies Available to sell. Suppose that P=20N+3600 gives P as a function of N for these available copies. Identify the correct description of the values in both domain and range of the function. Then, for each, choose the most appropriate set of values.

equation is p = 20n + 3600
p is her pay.
n is the number of copies she sold.
n is smaller than or equal to 140.
the domain is all values of n greater than or equal to 0 and smaller than or equal to 140.
the range is all values of p greater than or equal to 3600 and smaller than or equal to 20 * 140 + 3600 = 6400.

the graph of this function is shown below.
