math and logic question

[Bob Sacamano]

if it takes 7 people, 2 days to do a job

how many people would it take to do that job in half a day?

7 x 12?

If it takes 7 people 2 days to do the job, assuming all people are the same, it would take 14 people to do it in 1 day. So, it should take 28 people to do it in half a day...assuming that it's physically possible to do the job in half a day.

I was ****ing WAY off
as you can see, math is not my strong-suit, I sucked doing proofs in Geometry

YEAG, shut up

1.75 people.

28.
Divide the 2 days in 4 halves and multiply by 7.

Just for future reference Bob, this is how you can figure a problem like this out, regardless of the time or the amount of people.

You have the variables of # of people and of time, set to equal 1 job.

So, your basic equation looks like this:

(# people)(time) = 1 job

or

(P)(T) = J

In the problem, you are given a P and a T value.

(7)(2) = J
(7)(2) = 14

Now, since you know the "value" of a completed job, any further combination of variables must equal 14.

In the second part of the problem you are given only one of the variables, amount of time.

(P)(.5) = 14
(28)(.5) = 14

What, no accounting for efficiencies arising from economies of scale and division of labor?

I just assumed a Marxist society where labor divisions would be set up for maximum efficiency. Much like the government retooling of our auto-industry...or something.

1/2 a day is a 1/4 of 2 days.....so 4 is the multiplier. 4 x 7 = 28?

thanks mason

More or less correct.

 

[SLATEmosphere]

1.75 people.

Whaaaat? LOL..If it took 7 people to finish a job in 2 days it would take LESS people to finish it in shorter time?:laugh2:

Well...if the extra workers were from the government...

YEAG, shut up

Thats funny I struggled at proofs and geometry and breezed through Algebra I & II and I remember more of my stupid geometry and have used my Geometry more often.

 

[YosemiteSam]

The real question is how many CowboysZone forum posters would it take to do that same job in 2 days?

I'm not sure of the answer, but I do know that if Yeager is part of the work force, you have a one week penalty right off the bat. :laugh2:

Unlikely. You would be surprised how often people use Algebra everyday without even noticing it.

I aced trig, even had my math teacher persuade me to take AP Calculus

but for the life of me I was stumped trying to get through proofs, I think I eeked out a D in Geometry

so true
