<PRE><B>Question 375321</B>
An investor of a new product believes that the cost of producing the product is given by the function: 
C(x) = 1.75x + 7000 
How much does it cost to produce 2000 units of her invention? 
.
In this case, x is 2000
So, plug it in and solve:
C(x) = 1.75x + 7000 
C(2000) = 1.75(2000) + 7000 
C(2000) = 3500 + 7000 
C(2000) = $10,500</PRE>
