Answers
A) 202.5
B) 194.5
C) 197.5
D) 182.5
E) 177.5
For this it is easiest to use simple numbers. Let's assume that Elaine's annual earnings last year were $100.   She would've spent $20 of this on rent.   This year she earned 15% more, or $135.   She would've spent 30% of this on rent, or $40.5   Do $40.5/$20   This will give you 202.5%   202.5 is the correct answer.
