Answer:
[tex]7w+5s\leq 400[/tex]
Step-by-step explanation:
Money to be spent is not more than $400.
Cost of a case of water = $7
Cost of each sandwich = $5
Let number of cases of water bought be [tex]w[/tex]
Number of sandwiches bought be [tex]s[/tex]
From the question we get
[tex]7w+5s\leq 400[/tex]
The inequality which would determine how many sandwiches, and how many cases of water that can be bought is [tex]7w+5s\leq 400[/tex].
