Question 510688
{{{S[1] = k/T[1]}}} Solve for {{{T[1]}}}.
{{{T[1] = k/S[1]}}} 
Increase S by 50% to get {{{S[2] = (3/2)S[1]}}} so now you have:
{{{T[2] = k/(3/2)S[1]}}} Simplify the right side.
{{{T[2] = (2/3)(k/S[1])}}}={{{(2/3)T[1]}}} so...
{{{T[1]}}} has decreased by {{{1/3)}}} or {{{33}}}{{{1/3}}}%
