To find out how much of the mystery substance (m) Tim added to his experiment, we need to solve the equation 12.93 + m = 17.0.

Subtracting 12.93 from both sides of the equation, we get:
m = 17.0 - 12.93

m = 4.07

Therefore, Tim added 4.07 ounces of the mystery substance (m) to his experiment.

The correct answer is: A 4.07 ounces.
