See: Delta. And think: New minus Old, all over Old.
Think: your piggy bank. You reached down into its naughty places and, well, had to violate it to get your money out. At New Year's Eve last year, it had $28.36 in it. It's now a year later, and you do the same annual violation. You count $37.55. What's its delta, or rate of growth?
New: $37.55. So you subtract $28.36 from $37.55 and get $9.19. The old is $28.36...and you get about 32.4%. That's the rate of growth, year over year.
And yes, you can have a negative number as well: rate of shrinkage. Either way, they're rates of change.

sheik Shaper X nine two days a week Friday and
Saturday two out of seven twenty nine percent And the
whiff whisper only gets use once a week one out
of seven on the rate they're fourteen percent In real
life businesses can use the utilization rate to see how
efficiently they're using Their resource is like What if they
had a tractor smelter thing that was just sitting there
Not used four days a week But they may be
rented to another tractor smelter and make more money Something
like that Well really businesses can figure out how much
they operate equipment see if they have additional slack to
ramp up production And in that slack sometimes they can
run it out or do everything's with it and make
a fortune And if that's not the case well then
they can use it as an employee evaluation tool Like
by looking at a worker's utilization rate a company can
see if their employees time is getting applied effectively like

to take advantage of your vast knowledge of the industry
You contract your services to manufacturers test their products and
advise them on various high level Clipper related problems You
work forty hours a week but only twenty two of
those hours are pay billable hours working for clients The
rest of the time you're working on well marketing and
processing billing and watching YouTube videos about the history of
nose hair So you stay current on the industry so
that's twenty two of forty hours working with clients are
billing them for your time That's a utilization rate ofyour
time We're actually being paid for it of fifty five
percent Probably some room for improvement there right You really
need all that research Could you get more clients to

the Sheik shaper for work days It will get you
that more impressive cut for client meetings Yeah How'bout that
Hopefully you'll be able to jack up those billable hours
Increase the utilization rate for the sheik shape or to
eighty six percent Pretty much every day but Sunday Yeah
that'd be big Then maybe you can get your billable
hours utilization right above sixty percent Right You make a
lot more money If you do that after all a
few more clients And then you can afford a few
more collector clippers in the display case here Like the
Clipper Lincoln used before giving the Gettysburg or the Clipper
that Neil Armstrong took to the moon Remember the quote
One small clip for man You know something like that
