At most, Keith can spend $90 on sandwiches and chips for a company lunch. He already bought chips for $15 and will buy sandwiches that cost $6 each. The inequality 15 + 6s ≤ 90 represents the described cost, where s is the maximum number of sandwiches that could be bought. What is the maximum number of sandwiches Keith can buy?

Given :
15 + 6s ≤ 90
Where, s = number of sandwiches
6s ≤ 90 - 15
6s ≤ 75
s ≤ 75/6
s ≤ 12.5
So, Keith can buy 12 sandwiches.
