You wish to be able to handle 5 additional children on an emergency basis without a violation, what additional square footage is required?

Square footage for 5 children is____ square feet.

Answer 1

fun fun...

Answer 2

It's not so bad... just a bunch of steps.

Step 1: During hours of operation, 40% of the total 48 need space. What is 40% of 48?

Answer 3

Im thinking 48x0.40=19.20

Answer 4

Looks great so far :)

Answer 5

step 2: each child needs 35 square feet. You determined in step 1 that you have to provide space for 40% of 48 or 19.20 children.

So 19.20 children multiplied by 35 square feet per child is _______ ?

Answer 6

672

Answer 7

19.20x35=672

Answer 8

Good stuff... that's it for the first part.

Part 2 is basically the same, but easier... if you need 35 square feet per child, how much space do you need for 5 extra kids?

Answer 9

672 sq ft for the first one right

Answer 10

right :)

Answer 11

35x5=175

Answer 12

right... don't forget the units :)

Answer 13

do you turn these in on paper, or submit them online?

Answer 14

ok

Answer 15

they already writen i just have to put the number

Answer 16

yeah, I didn't notice that before... I just didn't want you to forget.... I have heard of people who get the right number but leave off the units and get marked wrong... I also heard of someone who forgot the comma, putting in something like 6000, and got it marked wrong even though the number was right (but the problem DID say to include the comma).

Answer 17

Good work overall... are you feeling better about how to work these problems?

Answer 18

wait it saying something not right

Answer 19

on part 1 or 2, or can you tell?

Answer 20

part 1 they got 700

Answer 21

part 2 is right

Answer 22

ok, arrgggh... sorry about that.

What they wanted you to do was to find 40% of 48 kids, which you did correctly and got 19.2. But what neither of us did was to say, "Hey, wait, I can't have a 0.2 of a kid, so I need to round up to a whole number of kids, like 20".

And then you multiply 20 x 35 to get 700 sq ft.

Answer 23

I thought, incorrectly it seems, that since the number 48 was just an average, and that 40% was an estimate of the number of kids, that it would be fine to leave it as 19.20.

The problem wasn't clear that way... but rounding up to 20 was apparently what they wanted you to do.

Answer 24

i took 19.20x35=672

Answer 25

yes, me too.

You were supposed to round 19.20 up to 20, then do 20 x 35 = 700

Answer 26

Answer 31

Im gonna call school on monday and ask them to give me my credit back because all my answers are right :)

Answer 32

yes... the first two are rounded to the nearest sq ft, just like the problem asked for.

And the price for the third part should be fine too.

That is weird :( School is enough of a challenge without having the system say you're wrong when you aren't.

Answer 33

i know but that's ok thank you so much for helping me. They can fix it on monday :)

Answer 34

I'm glad to help :) Good luck with it Monday :)

Answer 35

Thank you you come here a lot

Answer 36

Hopefully it's helpful for people who need it, plus I find that trying to help explain things is good practice... explaining often helps me get an even better understanding than I had before.

Anyway :) as I said, glad to help...

Answer 37

ok talk to you soon ill hit you up if i need more help. do i just send message if i need help or what

Answer 38

it's hard to work problems in the messages, but you can message me and then post the problem. You can tell if I'm online or not too... but if I am not online, just post your question anyway... there are a bunch of good people here.

Answer 39

ok thank you. bye.

Answer 40
