Ella bought some key chains and spent a total of $24 each key chain cost the same whole dollar amount. she bought between 7 and 11 key chains. how many key chains did ella buy?

 The correct answer is 8.

Step-by-step explanation:

To solve this problem we must find a number that is a divisor of 24.

The divisors of 24 are 1, 2, 3, 4, 6, 8, 12 and 24.

But they are asking us to have a number between 7 and 11, so the correct answer will be 8.

If we do 24: 8 it will result in 3, which means that each key chain has cost $ 3.

If you had any questions and made 7,8,9,10 and 11 divided 24, you could check that the only number that will result in an integer will be 8.

Given this information we can say that the correct answer is 8.

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11-1 > 1-1+a

-12 > a
