You are shipping a care package to your sister in college. It costs $0.85 per pound plus a flat-fee of $12 to ship the package. Write and use an algebraic expression to find the total cost of shipping a 7 pound care package.

Respuesta :

The expression should be
.85x+12=c. (C=cost, x=package in lbs)
And it would cost $17.95
.85(7)+12=
5.95+12=17.95
