You can do POE but you would rather spend some time solving for the solution than deciding between whats left after POE. If you know that you can solve, why guess.
Quick solution under 2 minutes:
1.11S + 0.99D = 1.02[S + d]
0.09S = 0.03D
S/D = 1/3
I am the master of my fate. I am the captain of my soul.
