Question

The formula C = 20W shows how much the cost, C, of sending a letter by first-class mail depends on the weight of the letter, W. (C is measured in cents and W is measured in ounces.) So, we consider
C a function of W and write C(W)=20W. Find
C (2), C (3), and C (4). What is the domain of function C ?

Answer 1

Answer:

Domain:0 is more than or equal to W

C(2)=40

C(3)=60

C(4)=80

yeeeeeaaaaaahhhh
