are you having trouble with understanding which values go into the equation? or how to solve the equation after plugging in the values?

A = A0 x e^kt ||A = final amount (64%), A0 = initial amount (100%), k = ln (0.5) / (half life) ...this comes from half life equation so it becomes k = ln (0.5) / 17, t = time (solve for this) || 64 = 100 x e^[(ln (0.5)/17)t] || ...now solve for t
