a university will spend at most $4,500 to buy monitors and keyboards for a computer lab.Each monitor will cost $250, and each keyboard will cost $50
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 buying monitors can be represented by the inequality 250x, where x represents the number of monitors.
The cost of buying keyboards can be represented by the inequality 50y, where y represents the number of keyboards.
Since the university will spend at most $4,500, the total cost of buying monitors and keyboards should be less than or equal to $4,500.
Therefore, the inequality that represents all possible combinations of x and y is:
250x + 50y ≤ 4500
