If you would like to know how much do they have 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 = 35.8
r = 135% of t = 135% * 43 = 135/100 * 43 = 58.05
t + j + r = 43 + 35.8 + 58.05 = 136.85
They have 136.85 in total.
