I'll try to explain what I need! Got a dog show where people send in an entry form with their dog details on - because of restrictions we are limited to the number of people (not dogs) so I need to have a rough estimate of how many people will be entering. We reckon roughly 1.5 dogs per entry form (some are joint owners) so say we had 800 dogs entered how would we work out how many people that would be if it was 1.5 dogs per form. Does that make any sort of sense?

so if each person brings 3 half dogs, divide 800 by 3 and that will tell you how many people.
no i am wrong... 800 dogs is 1600 half dogs so that is the number you divide by 3

Thanks, I get a mental block with anything to do with maths.
800 divided by 1.5 would tell you the number of entry forms but you need to estimate the average number of owners on each form.

So turning it round, if I want a maximum of 700 people how many dogs would that be using the above formula?
800 ÷ 3 X 2 = 533.33
cant you just ask people to specify how many people will be with the entry?
Depends how many people on average come with each dog
Question Author
ff most are single owners, but a few are joint but of those some will have more than the 1.5 dogs, even up to five or six each. Overall it will roughly even itself out if we go by number of entry forms.
700 X 1.5 = 1050
then there's no working out at all (just adding up)
If on average each person brings 1.5 dogs then 700 people would bring 700 x 1.5 = 1,050 dogs
Question Author
Thanks, that is the answer I really wanted!
To do these think how many dogs there would be if all 700 people brought one each. Answer 700 x 1 =700.
Then think what it would be if each brought 2 dogs. 700 x 2 = 1400.
So then what calculation do you do if each brings 1.5. Answer will be half way between 700 and 1400
Question Author
Thanks, that I can understand!
Why not stipulate number of adults that can attend.

Then ask how many intend coming.

Then ask how many additional persons would like to attent IF there is spare capacity.
Nor adults but persons (as a baby in a pram would count towards your total!)
State that there will be NO unauthorised entry - no ticket/name on list, they're not getting in!
