Answer 1

Explanation:

We are told that the music club is having a bake sale as a fundraiser. They sell x brownies at $5 each and y cookies at $8 each. They will sell at least 26 brownies and 15 cookies.

We can represent this information as:

`x\geq 26`

`y\geq 15`

They need to make at least $250. We can represent this information as:

`5x+8y\geq 250`

Therefore, our system of inequalities will be:

`x\geq 26`

`y\geq 15`

`5x+8y\geq 250`.
