Ella bought some key chains and spent a total of $24. Each key chain cost the same whole-dollar amount. Shae bought between 7 and 11 key chains. How many key chains did Ella buy?

See I’m this case you cannot set up a equation , but what you can do is find a number between 7 and 11 that can be multiplied by a number and equal to 24 , so in this case the answer is 8 because 8 can be multiplied by 3 which equals 24
