You can put this solution on YOUR website! A delivery company's charge for an overnight package weighing in excess of one pound is given by the formula c=2.83w + 15.51, where w is the weight of package in pounds.
A 5 lb package cost 29.66
A 12 lb package cost 49.47
A 20 lb package cost 72.11
:
A package that cost 164.07 to mail weight about ______ lbs.
substitute 164.07 for c in the equation: 2.83w + 15.51 = c; solve for w
:
2.83w + 15.51 = 164.07
:
2.83w = 164.07 - 15.51
:
2.83w = 148.56
w =
w = 52.5 lbs
;
:
Check solution by putting 52.5 for w in the original equation:
c = 2.83(52.5) + 15.51
c = 148.58 + 15.51
c = 164.09, we round off the weight hence a 2 cent difference
