Let
and
. By the product rule,

By the power rule, we have
and
, but
are functions of
, so we also need to apply the chain rule:


and we have


So we end up with

Replace
to get everything in terms of
:

We can simplify this by factoring:


14 x 3/4 = 42/4 = 10.5 lbs
1 lb = 450 g...so 10.5 lbs = (10.5 x 450) = 4725 g.....1 g = 0.001 kg....so 4725 grams = (4725 x .001) = 4.725 kg
so ur gonna need a medium sized turkey.....4.725 kg...at 5.99 per kg =
(4.725 x 5.99) = $ 28.30 <==
