Two shipping companies charge different amounts to mail packages. UPS charges
an initial $5 fee, and each pound shipped is an additional $1. Fed Ex charges an
initial $3 fee, and $1.50 for each pound shipped.
a.) How much would each company charge to mail a package weighing 2
pounds?
b.) For what weight package will the two companies charge the same amount?
c.) Which company charges less for a 6-pound package? How much will you
save by choosing this company to ship your 6-pound package?
