Final answer:
The statement "It costs $10 to ship a 5 lb package" in function notation is written as C(w) = 10, where C is the cost function and w is the weight.
Step-by-step explanation:
To write the statement "It costs $10 to ship a 5 lb package" in function notation, we define a function to represent the cost of shipping based on the weight of the package. Let's call the function C(w), where C stands for cost and w stands for the weight of the package in pounds. Since the cost is fixed at $10 for a 5 lb package, the function can be written as:
C(w) = 10
This function notation implies that no matter the input for weight w, if the package weighs 5 lbs, the shipping cost will always be $10.
