Jill is inviting friends for
a party, She doesn't know
any of their birthdays. What
is the least number of friends
that she needs to invite in
order to guarantee that at
least a of the friends will
I have a birthday in the same month?

13.

Step-by-step explanation:

If each of the first 12 guests happens to be born in a different month, the 13th person will have to be born in the same month as one of the first 12.

step-by-step explanation:

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,

hope it
