federal express charges lucy $18 for pick up and then asses a fee of $1.45 per lb to ship a package. Write an equation that shows the relationship between the total shipping charge (c) and the total weight (w) of the package

Answer 1

Savannah,

 

In this case, the relationship between C and w is linear in the form y=mx+b where m is 1.45 and b is 18 (base charge). Thus C=1.45w+18
