POTD - 7/19

So what happened on Friday? I finally got you?? Only links gave it any sort of a shot. Disappointing. So I'm posting it again to give you a shot at redemption...

 

TODAY:

 

1. Try Again

 

 

2. Two-thirds of the people at a concert are wearing hats. Of those who don't wear hats, three-fifths wear T-shirts. If the number of people at the concert without a hat or t-shirt is 200, how many people attended the concert?

I tried 1 on Friday, didn't get any farther than guesses for the words. No clue how to put them in that box.

 

But 2, I believe is:

 

1500

1500*(1/3)=500 (people without hats)

500*(2/5)=200

1500*(1/3)=500 (people without hats)

500*(2/5)=200

 

or:

 

(1-3/5)*(1 - 2/3)x = 200 (the fraction of people without hats and (multiply) people without t shirts whom attended the concert (x) was 200)

 

(2/5)(1/3)x=200

 

2/15x=200

 

x=200*(15/2)

 

x=3000/2

 

x=1500

I'm right at the same number as the rest of you, with the slightly different approach (not all that different, but one extra step to spell it out a bit more).

 

x=# people without hats

Two fifths of the people without hats are also without t-shirt, so:

200=(2/5)x

x=500 people without hats

 

That's one third of the people at the concert, so there are 1,500 people total

(unless it's a nickelback concert and all that white trash aint wearin no shirts or shoes :blink: )

I just noticed they have a show coming up Nashville in September. What's that, like a 4 hour drive for you? Definitely worth it for the chance to see living rock and roll legends in their prime. :devil:
