125 mg of solid drug is placed in solution. Over time the drug dissolves. The amount of undissolved drug in mg was monitored as a function of time in minutes. The data was graphed with the following results:

Amount of drug remaining vs. time: best fit is y = -11.4x + 125 R²
= 0.990 ln(Amount of drug remaining) vs. time: best fit is y = -0.114x + 4.84 R²
= 0.976

How much drug (in mg) remains after 5 minutes?
