Answer:
An inequality to determine how many sandwiches he can buy is
and no. of sandwiches he bought is 9 .
Step-by-step explanation:
Let x be the no. of sandwiches he can buy
Cost of 1 sandwich = $4.50
Cost of x sandwiches = 4.50x
He already bought chips for $6
At most, Kyle can spend $50 on sandwiches and chips for a picnic.
So, ![4.50x+6\leq 50](https://tex.z-dn.net/?f=4.50x%2B6%5Cleq%2050)
![4.50x \leq 50-6](https://tex.z-dn.net/?f=4.50x%20%5Cleq%2050-6)
![4.50x \leq 44](https://tex.z-dn.net/?f=4.50x%20%5Cleq%2044)
![x \leq \frac{44}{4.50}](https://tex.z-dn.net/?f=x%20%5Cleq%20%5Cfrac%7B44%7D%7B4.50%7D)
![x \leq 9.78](https://tex.z-dn.net/?f=x%20%5Cleq%209.78)
Hence an inequality to determine how many sandwiches he can buy is
and no. of sandwiches he bought is 9 .
