Murphy the dog plays a game with himself based on whether he spends more time on a given day lying in the living room or lying in the dining room. The equation 22l + 31d = 1823 represents this situation, where d is the number of days when he spends more time lying in the dining room and l is the number of days when he spends more time in the living room. How many more points does Murphy award himself on a day when he spends more time lying in the dining room versus on a day when he spends more time lying in the living room?

The correct answer is 9.

There will come a point within your test training when you will immediately recognize this as what we call an Understanding Equations(UE) question. If that point is now, and you rather effortlessly typed in 9 as your answer, we’ll talk again elsewhere.

If you thought you were supposed to solve something here, it’s understandable, but this is one of the many questions that reveal how particular what we’re doing here often is. At the heart of UE’s in general is the idea that we are interpreting. At the heart of this particular UE is what a coefficient can reveal.

The coefficient in front of the ‘l’ indicates that Murphy awards himself 22 points on living room days. The coefficient in front of the ‘d’ indicates that Murphy awards himself 31 points on dining room days. Our correct answer of 9 is a byproduct of subtracting 31 and 22.

We can all eventually see why this question can be initially missed.

We can all eventually see why questions like this one can be universally smashed.

And, if you ever have the incredible opportunity to meet Murphy the dog, we can all see why he is beloved.🤟🏽🐕‍🦺
