a shipping company charges $40.00 for a 10 lb package.
Another company charges $22.85 for a 3 lb package.
Write a formula to show the cost for shipping per company and the cost per pound.
-------
1st company:
C(x) = (40/10)x
C(x) = 4x where x is a pound to be shipped
-----------------------------------------------
2nd company:
C(x) = (22.85/3)x
C(x) = 7.62x where x is a pound to be shipped
