Answer 1

You find the number between 7 and 11 that can divide evenly into 24. 8 is the only number between 7 and 11 that can divide evenly by 24. She bought 8 keychains at the price of 3 dollars each.

Answer 2

Answer: Ella bought in total of 8 key chains.

Explanation:

We are given:

Total cost of the key chains = $ 24

Number of key chains are between 7 and 11 and each key chain cost the same whole number value.

This means that, the number of key chains must be a factor of 24.

Factors of 24 = 1, 2, 3, 4, 6, 8, 12, 24

The number which is a factor of 24 and is present between 7 and 11 is '8'

So, Ella bought in total of 8 key chains.
