Question

An executive buys $2490 worth of presents for the children of her employees. For each girl she gets an art kit costing $33; each boy receives a set of tools costing $29. How many presents of each type did she buy?

Answer 1

Don't tell me a mod has schoolwork! :O

Answer 2

Haha. Why? Don't they study?

Answer 3

I thought of mods as some kind of voodoo god that goes in a cape and flys in the air with their purple helmet of copper and steel.

Answer 4

We are but like Superman, we often operate undercover.

Answer 5

how many total children are there ?

Answer 6

33g + 29b = 2490
There is one equation.
How many kids in total ?

Answer 7

let there be 'g' girls and 'b' boys.
33g + 29 b = 2490
you need more info.

Answer 8

No idea.

Answer 9

do you have choices ?

Answer 10

It's a book question

Answer 11

My closest guess was 40 for each @hartnn

Answer 12

It's harder to get a higher SmartScore if you NEVER ask a question.

All Girls
$2490 / 33 = 75.45

All Boys
$2490 / 29 = 85.86

So, somewhere between 75 and 85 total gifts.

Answer 13

would it be g = g - b ? Does that make sense ? Could that be the first equation ? Then sub g - b in for g ?

Answer 14

I think it will give you the same equation?

Answer 15

So guys? No idea? :/

Answer 16

33g + 29b = 2490
g = g - b

33(g - b) + 29b = 2490
33g - 33b + 29b = 2490
33g - 4b = 2490
33g = 2490 - 4b
g = (2490 - 4b)/33
g = 75 - 4b/33

well...this is not working....sorry I don't know

Answer 17

No problem chic. XD

Answer 18

@jim_thompson5910 .....lets see if you can do this one :)

Answer 19

More screenshots

Answer 20

I know, @tkhunny. I was just joking ;P

Answer 21

haha @Mertsj

Answer 22

Saw it already. Unfortunately they haven't answered the question. :/

Answer 23

Honestly I thought that the mods were just lazy guys just sitting back who rarely even use the site ;P

Answer 24

Lol. There are all types of people and all types of mods too. ;)

Answer 25

Thats why the moderation is so bad, esp. in areas like the Music section/chat. I'm still kinda mad about this. Even in the math chat things get CoC-violated.

Answer 26

@dumbsearch2 This is America...you have a right to be wrong.

Answer 27

^

Answer 28

W-O-W.
Then what's the point of mods ?

Answer 29

Today, with my VERY OWN EYES, I witnessed tons of inappropriate chat stuff.

Answer 30

To keep the wrong thing in limits or on track? Maybe?

Answer 31

Your eyes were deceiving you. XD

Answer 32

Oh. My screenshot tool doesn't deceive me xD

Answer 33

its alright.
this won't change.
it's been like this for months.

I'll stop my ramblings.
Go back to what you were doing (:

Answer 34

oh, so this is the problem of diophantine equations...
stop arguing ?

Answer 35

But your eyes do. :P

People are thinking about it i guess..

Answer 36

\[x = \text{number of girls}=\text{number of knits}\\
y = \text{number of boys}=\text{number of tool kits}\\
33x+29y=2490\\
x+y = N\\
33x+29(N-x)=2490\\
4x=2490-29N\\
x=622.5-29{N\over 4}
\]
hint 1: N must be an odd integer

Answer 37

i.e., there are in all a odd number of children

Answer 38

now,
\[622.5\ge 29{2n+1\over 4}\]
