If you would like to know how much money did they collect in total, you can calculate this using the following steps:

Travis ... t = $43
Jessica ... j
Robin ... r

120% of j is t
120% * j = 43
120/100 * j = 43
j = 43 * 100 / 120
j = $35.83

r = 135% of t = 135% * 43 = 135/100 * 43 = $58.05

t + j + r = $43 + $35.83 + $58.05 = $136.88

The correct result would be C. $136.88.
