1.)Sales (in millions) of a company are modeled by the expression for x items produced and sold (in millions). If 4 (million)items are produced and sold, what would the sales be?
I AM NOT SURE HOW TO SET THIS UP.
x = 4 in that case
To find the sales for 4 million items produced and sold, let's assume that the expression for the sales is given by S(x), where x represents the number of items produced and sold in millions.
Let's say Sales (in millions) is given by the expression S(x).
To find the sales when 4 million items are produced and sold, you substitute x = 4 into the expression for S(x):
Sales (S) when x = 4 = S(4)
Substitute x = 4 in the expression for S(x) and calculate the value of S(4).
