How do you write a real-world scenario that could be represented by the inequality 4x + 2y 40 and how are you supposed to choose one ordered pair that is a solution to the given inequality and explain what that ordered pair means in the context of your real-world scenario. It doesn't make sense could you explain it. Please and Thank You!

it's supposed to be greater than or less than 40

It can't be greater than or less than. That doesn't make sense. Please check that.

I checked the equation is 4x + 2y greater than or equal to 40 sorry!

A situation could be that you have to buy two objects, sunglasses and earrings and have to spend 40 or more dollars. It's not realistic, but you could alter it into something like that. Usually you would have a budget, so it would be easier doing less than or equal than instead of greater than or equal to. x could be the cost of one item, and y would be the cost of the other. The co-efficients (numbers in front) would be how many of each you bought.
