Answer:
Option (c) is correct.
f(x) = 5 + 0.04x
Step-by-step explanation:
Given : The cost to mail a package is $5 for the first 2 pounds and 40 cents for each additional ounce.
We have to choose out of given functions that represents the cost to mail a package if x is the number of ounces over 2 pounds.
Consider f(x) represents the cost to mail a package if x is the number of ounces over 2 pounds.
Given : x is the number of ounces over 2 pounds that is over 2 pounds the package mail has x ounce.
100 cent = $1
Also, they charge 40 cents for each additional ounce
Thus for x ounce they charge = $0.4x
Thus, f(x) = 5 + 0.04x
Thus, Option (c) is correct.
