Let d be days needed for Rhea's account to have more than Trisha's.
350 + 25d < 200 + 35d (Trisha's account is on the left and Rhea's is on the right)
150 < 10d (simply by putting variables on one side and constants on the other)
15 < d (solving for d)
It will take 15 days for Rhea's account to pass Trisha's
