I have worked this out to be that mary would need 5 table for 10 people. 15 tables = 30 people, 25 tables = 50 people, 50 tables = 100 people
i worked this out by haveing 1 table = 2 people
Daniel, a good start to the answer but you have not thought it through thouroughly. Maybe you could give it another go.
10 people = 4 tables, 4 people on each side and 1 on each end because the tables are joined together.
30 people = 14 tables, 14 people on each side and one on each end.
50 people = 24 tables, 24 on each side and one on each end.
100 people = 49 tables, 49 people on each side and one on each end.
i have had another go
4 tables = 10 people
14 tables = 30 people
24 tables = 50 people
49 tables = 100 people
my first answer was wrong because i didn't put any people at the end s of the tables. this time i have put people down each side and at the ends of the table
Good to see you are thinking a little more carefully Daniel. I will post the answer tomorrow. Maybe you are right, maybe not. You will just have to check after 5 tomorrow.
PS
Daniel please use capital letters.
Good thinking Rachel, your answer was perfectly correct. I will have a prize for you when we get back to school. Daniel, good to see you re-thought your answer. I might have a small prize for you as well as you were willing to have a second go at the answer.
There will be a new maths problem posed tomorrow.
I think Mary would have 5 tables for 10 and on the last table it has 1 person.
15 tables for 30 and on the last table it has 1 person.
25 tables for 50 and on the last table it has 1 person.
50 tables for 100 and on the last table it has 1 person.
when i was thinking in the end 3 people were on the end and to in the middle!!
I think the answers are 3r2,8r2,
13r2 and 25 square tables.
