Respuesta :
To solve this problem, you need to use a process of trial and error, and add up each number until you get 24 or above. If you get above, it is wrong. The only number that goes into 24 evenly is 8, so the answer is 8 keychains.
Answer: there are 8 key chains Ella can buy.
Step-by-step explanation:
Since we have given that
Ella bought some key chain and spent a total of 24.
Each key chain cost the same whole dollar amount she bought between 7 and 11 key chains.
As we know that between 7 and 11, there is only 1 number which is factor of 24 i.e. 8
Hence, there are 8 key chains Ella can buy.
