This guy Darryl has 7700 on investments after a year so he put money into the
investment account I recommend a Roth IRA and when you're young you want to do
aggressive growth that means you're buying companies that are fairly new and
there have potential for growing that way you'll make lots of money that way
and then the level off and then when you get older you could just get regular
growth because you know they're established like Microsoft and Apple so
they're not gonna jump in growth because they're already so high this guy will
just say but we'll go over that stuff later so Darryl has seventy seven
hundred dollars an investment account after a year he earned 10% during that
year that means now after a year he has this much money
that means the year before that he didn't have that much money
he had something made 10% and now he has seventy seven hundred dollars so if you
were to take a look at this as like say a picture
here's his money that's how much money he put in at the beginning of the year
at the end of the year he had an extra 10% so that is the extra and we know
overall it turns out to be seven thousand seven hundred dollars so by
looking at the picture what is that $7,700 represent yes look at that you're
not looking at the picture you're not you're still not looking at the picture
what is the whole thing you're not looking at the picture yes
so what is that what is a hundred percent plus ten percent extra no I mean
in percents I want to know what this is gonna be there you go so that whole
thing represents a hundred and ten percent that is what you should have
written down as your first thing so now we want to fight what is the question
asking so they want to know this they want to know how much he had at first so
the question is how do you turn a hundred and ten into a 100 you're gonna
have to divide I look at this and I see an eleven here and I see a 77 there
what can you divide those by oh I can divide this by eleven so I'm gonna
divide this side by 11 so 11 divided by eleven is a one with a zero at the end
of it how'd he turn to ten into a hundred
times if I what time's it by 10 multiplied by ten so you do the same
thing on this side divided by eleven well 77 divided by eleven is just seven
isn't it with two zeros after it so he had extra $700 because that's what 10%
is and then he multiplied by 10 so that's seven with how many zeros after
it count three so this guy Darryl had seven thousand dollars in his account
so this is the thing that you're learning today how to figure that out
best way to do it maybe draw a picture for it and then look at the picture and
say what does this show me well it shows the $7,700 is after the year this is how
much he had before this is how much he had extra now he has 7700 so that means
the whole thing must be like she said 110 110 they want to know the original
amount original means what hundred percent so you figure out how to turn
110 into a 100 once you could do that then you can figure this out do the
exact same thing yes mm-hmm exactly so every single problem is gonna
be just like this just realize on a test I'm not gonna tell you you're gonna be
doing it this way you have to figure out and say oh I wonder if this how do I
know if I'm gonna make this into a hundred percent or make this into more
than a hundred percent that's what you got to figure out so look at these word
problems will give you words to let you know to do it this way your job is to
figure out what those words are to help give you that hint to do it this way so
now you know how to do all them all right you're gonna have to do it this
way
