Question

Mr. Clark plans to spend no more than $400 on sandwiches and water for a work meeting. Each case of water costs $7.00 and each sandwich costs $5.00. Which inequality would Mr. Clark use to determine how many sandwiches, s, and how many cases of water, w, he can buy?

Answer 1

`7w+5s\leq 400`

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
`w`

Number of sandwiches bought be
`s`

From the question we get

`7w+5s\leq 400`

The inequality which would determine how many sandwiches, and how many cases of water that can be bought is
`7w+5s\leq 400`.
