United Shipping Package Service charges a flat fee of $6 plus $0.15 per pound to ship a package anywhere in the continental U.S. Trey is not sure of the exact weight of his package, but knows that it weighs at least eight pounds. What is the minimum cost Trey can expect to pay for shipping the package?
Answer provided by our tutors
Let x represent the weight of the package
x >= 8
Tray will pay:
6 + 0.15x >= 6 + 0.15*8 = $7.2
The minimum cost that Trey can expect to pay is $7.20.
