Question 24118: The cost of sending an overnight package from speedy air is $15.00 for the first pound and 3.00 for each additional pound. How much will it cost to send a 7 pound package? it is telling you to assign labels to the parts of the verbal model, use the labels to translate the verbal model into an algebraic model then solve the model..ive done the first step but the rest is throwing me completely off could you please help me?? thanks a million!
Answer by stanbon(75887)   (Show Source):
You can put this solution on YOUR website! Let "x" represent the weight, in pounds, of any package.
Cost to send the package = cost of 1st pound + cost of additional pounds
Cost for x pounds = $15 + $3(x-1)
C(x) = 15+3(x-1)
If x=7, C(7)=15+3(7-1)
C(7)=15+3(6)
C(7)=33 (The cost to send 7 lbs. is $33)
Cheers,
Stan H.
