A shipping service has four different options for packages where each service has a base price for the first pound and a charge for each additional pound. Let w be the weight of the package in pounds and C be the cost in dollars. Match the solution that is viable for each equation. C=14.20+1.10w C=2.80+0.55w
C=23.35+1.85w
C=7.10+0.65w
need to match to
