Hanish will have 1 unit and Jeslyn will have 3 (because she is left with three times more than him). Add the money they both spent and the model will be of the same length (because they both had the same amount of money at first). The difference in the money spent by the two of them is equivalent to 2 units. You can then find the value of one unit which is how much Hanish has left. Multiply by 3 and Add $57.60 to find what Jeslyn had in the beginning
