A university will spend at most $3,000 to buy monitors and keyboards for a computer lab. Each monitor will cost $200, and each keyboard will cost $25.

Which inequality represents all possible combinations of `x,` the number of monitors and `y`, the number of keyboards, the university can buy for the computer lab?

The cost of the monitors is given by $200x, and the cost of the keyboards is given by $25y. The total amount spent should be at most $3,000, so the inequality is:

$200x + $25y ≤ $3,000
