Explanation:

Step1: Calculate start value

$4.2 + 16.07 = 20.27$

Step2: Move to matching result

From START, take path to $19.6 - 8.04$

Step3: Calculate next value

$19.6 - 8.04 = 11.56$

Step4: Move to matching result

Take path to $16.8 + 77$

Step5: Calculate next value

$16.8 + 77 = 93.8$

Step6: Move to matching result

Take path to $13 - 4.08$

Step7: Calculate next value

$13 - 4.08 = 8.92$

Step8: Move to matching result

Take path to $42.18 - 2.49$

Step9: Calculate next value

$42.18 - 2.49 = 39.69$

Step10: Move to matching result

Take path to $37.6 + 5.08$

Step11: Calculate next value

$37.6 + 5.08 = 42.68$

Step12: Move to matching result

Take path to $45.83 + 7.4$

Step13: Calculate next value

$45.83 + 7.4 = 53.23$

Step14: Move to matching result

Take path to $9.3 - 8.27$

Step15: Calculate next value

$9.3 - 8.27 = 1.03$

Step16: Move to matching result

Take path to $46.1 + 5.07$

Step17: Calculate next value

$46.1 + 5.07 = 51.17$

Step18: Move to matching result

Take path to $90.02 - 8.6$

Step19: Calculate next value

$90.02 - 8.6 = 81.42$

Step20: Move to final result

Take path to END!

Answer:

The correct path is:
START ($4.2 + 16.07$) → $19.6 - 8.04$ → $16.8 + 77$ → $13 - 4.08$ → $42.18 - 2.49$ → $37.6 + 5.08$ → $45.83 + 7.4$ → $9.3 - 8.27$ → $46.1 + 5.07$ → $90.02 - 8.6$ → END!
