I found this question to be helpful to write out the math of the stimulus.
(M1990 - C 1990 + M1991 - C1991 ) < (M1990-C1990)
The performing basic math. The M1990 and -C1990 are on both sides so those cancel out.
We are left with:
M1991 - C1991 < 0
M1991 < C 1991
I have been working on understanding which #% problems are best solved with basic math and which are not.
I haven't worked out a full fledged system yet but for this problem it really was the best way to solve it IMO.
The intuition of the above explanations are great too but for me personally I found the concreteness of the math much faster and easier to see.
