LAST QUESTION FOR TODAY!!!!! PLEASE!!!!!!

Part 1: Use complete sentences to describe a real-world scenario that could be represented by the inequality 4x + 2y >= 40.
Part 2: 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.

Answer 1

Part 1)

You have a test. There are two types of questions: multiple choice and true false. There are 4 options per multiple choice question and 2 choices per true/false question. Now say that you know that you got at least 40 points on the test. So if that's the case, and there are x multiple choice questions and y true/false questions, then this means that

4x+2y >= 40

--------------------

Part 2)

The ordered pair (10,2) is a solution since

4x+2y >= 40
4(10)+2(2) >= 40
40+4 >= 40
44 >= 40

is true. This would then mean that you got 10 multiple choice and 2 true/false questions correct.
